Etymology: —The specific epithet refers to the type locality Jichou Mt., a mountain range at the border between Jiulong County and Kangding City of Sichuan Province, China. Distribution, habitat, and ecology:— Allium jichouense is currently known from the type locality in Jiulong County and nearby Zimei pass of Gonggashan Township in Kangding County of Sichuan Province. Geographically, A. jichouense is sympatric with its closest relative A. sikkimense, as well as A. forrestii and A. changduense. It grows exclusively on alpine screes or gravelly slopes at higher elevations of 4,300 –4,500 m, and exhibits several morphological adaptations to the scree habitat, such as dwarf form, often falcate or curled leaves, commonly colored aboveground parts (including leaves, scape, spathe-valves and flowers), extended rhizomes and well-developed deep roots, demonstrating the well coevolution between scree plants and environment (Musarella et al. 2020)., Published as part of Huang, De-Qing, Sun, Hang & Ma, Xiang-Guang, 2022, Allium jichouense (Amaryllidaceae), a new species of the section Sikkimensia from southwestern China, pp. 115-128 in Phytotaxa 575 (2) on page 122, DOI: 10.11646/phytotaxa.575.2.1, http://zenodo.org/record/7413164, {"references":["Musarella, C.

Allium jichouense from Sichuan Province, southwestern China is described as a new species. It grows exclusively on alpine screes or gravelly slopes at higher altitudes of 4,300–4,500 m. Morphologically, it resembles A. sikkimense in bulb and floral features, but differs significantly in its falcate or curled, commonly reddish-purple pigmented leaves, scapes and spathe-valves. Phylogenetic analyses confirm that the new species belongs to A. sect. Sikkimensia and is nested within different populations of A. sikkimense. The possible scenarios are discussed for the embedded phylogenetic relationship of A. jichouense within A. sikkimense. A detailed morphological description, illustrations and habit features of the new species are given.

4.2. Tulipa tschimganica Botschantz. in Bot. Mater. Gerb. Inst. Bot. Zool. Akad. Nauk Uzbeksk. S.S.R. 16: 10 (1961). Type:— UZBEKISTAN. Grown in the Botanical Garden of the Academy of Sciences of Uzbek SSR from bulbs collected by Z.P. Botschantzeva in 1959 in the gorge in piedmonts of Greater Chimgan, on fine earth among stones, Botschantzeva 99 (holotype TASH 000526!). Description:—Bulb ovoid, 1.5–3.5 cm thick; tunic papery, blackish-brown, the inner surface sparsely covered with long and straight, adpressed hairs, more densely at the apex and the base; stem 15–25 cm long, the upper part of stem and peduncle pubescent, covered with a glaucous ealily fading bloom; leaves 3–4, relatively approximate, falcately deflected, grooved, not curled (sometimes slightly undulate), more or less pubescent, at the early stages of flowering often exceeding the flower; basal leaf broadly lanceolate, up to 7.5 cm broad; flower solitary, cup-shaped or starshaped; perigone segments 5–7 cm long, red with a yellow basal blotch or yellow with red W-shaped blotches on the inside; outer segments narrowly to broadly lanceolate, attenuate at apex, in yellow-flowered form usually red on the back; inner segments oblong or narrowly ovate with a more or less rounded, often notched apex; stamens nearly half as long as the tepals; filaments thin, slightly dilated at the base and pointed below the anthers; anthers 2–4 times as long as the filaments, yellow with brown apex or brownish, gradually and slowly opening from apex to base, but not becoming twisted or strongly incurved; pollen yellow or brownish, ovary narrowing at the base; capsule 1.5–2.0 cm broad and up to 11 cm long, narrow conical, elongated at the top, with a long beak (up to 3.5 cm), yellow (Fig. 10B). General distribution:—Chatkal and Karzhantau ranges (Kazakhstan, Uzbekistan). Distribution in Uzbekistan:—I-1 Western Tian-Shan district (I-1-b Western Chatkal region). Phenology:—Flowering: April–June (at least two weeks later than T. kaufmanniana); fruiting: May–June. Ecology:—Gravelly and stony slopes, deep valleys that are later cleared of snow, in middle mountain zone, 1400–2300 m a.s.l. Etymology:—The species is named after Chimgan Mountains, a mountain massive located in the western spurs of Chatkal Range 80 km from Tashkent, from where this tulip has been discovered. Chimgan is a famous mountain resort and one of the most important botanical regions of Uzbekistan with rich flora and a significant number of rare and endemic species. Note:— Botschantzeva (1962), Raamsdonk et al. (1997), Pratov et al. (2006) and Zonneveld (2009) regarded T. tschimganica as a separate species of T. sect. Spiranthera. According to Vvedensky & Kovalevskaja (1971), this species is a hybrid of T. greigii and T. kaufmanniana. Zonneveld (2009) assumed that T. tschimganica may be the result of hybridization between T. dubia and T. kaufmanniana in the wild. According to Phillips & Rix (1981) and Christenhusz et al. (2013), this taxon takes an intermediate position between T. dubia and T. kaufmanniana and can be considered as a natural hybrid. Before, at previous publications Tojibaev (2010) and Tojibaev & Beshko (2014) regarded it as T. kaufmanniana subsp. tschimganica. According to J.J. de Groot’s communication, T. tschimganica under conditions of cultivation differs with large bulbs, notable bigger than bulbs of T. kaufmanniana and T. dubia.

1.1. Tulipa tubergeniana Hoog in Gard. Chron., Ser. 3, 35: 358. (1904). Type:— Illustration in Supplement Gard. Chron., Ser. 3, 35, 4 April 1904 [lectotype designated by Christenhusz et al. 2013: 315]. Description:—Bulb ovoid, 3–5 cm thick, tunic grayish brown or brownish, papery, on the inside thickly lined with very fine hairs and looks like a ball of cotton wool; stem (5) 15–30 cm long, the upper part of stem and peduncle pubescent; leaves (3)4, approximate, deflexed, undulate at margins, curled, glaucous, more or less pubescent, ciliate, exceeding the flower; basal leaf lanceolate, (l.5) 2–4 cm broad; flower solitary, red; perigone segments 2.5–10 cm long, gradually acuminate, with a white pubescent tip (longer on the outer tepals than on the inner ones), the basal blotch oblong, commonly acute, black with pale yellow margin; outer segments rhomboidal or deltoid, slightly broader than the obovate or oblong inner segments; stamens one-third the length of perigone; filaments glabrous, flattened and black; anthers blackish-purple, longer than the filaments; pollen yellow; ovary green, slightly shorter than stamens, commonly with a violet bloom, tapering towards the tip; stigma sessile, much broader than ovary, usually purple; capsule oblong with brownish stripes. General distribution:—South-Western Pamir-Alay (Tajikistan and Uzbekistan). Distribution in Uzbekistan:—I-6 Western Hissar district (I-6-c Baysun region; I-6-d Kuhitang region; I-6- e Surkhan-Sherabad region), I-7 Hissar-Darvaz district (I-7-a Sangardak-Tupalang region), I-8 Panj district (I-8-a Babatag region). Phenology:—Flowering: April; fruiting: May–June. Ecology:—Clayey and variegated gypsy slopes in foothills and lower mountain zone, rarely in middle mountain zone, 400–1600(1800) m. Etymology:—The species is named after famous Dutch gardener C. G. van Tubergen (1844–1919). Note:—This is one of the highly ornamental species of Tulipa sent to Europe from southern Uzbekistan in the early 19th Century. The history of the journey of this tulip from Uzbekistan to Europe is associated with the name of Austrian (or German) entomologist J. Haberhauer (1828–1902). According to available data (Wilford 2006), this tulip was among the species sent for van Tubergen from Bukhara by Haberhauer during his travels to Central Asia (1861–1862). The species has been described in Gardeners Chronicle (Hoog 1904) by J. Hoog who noted that «… the species was recommended an Award of Merit at a meeting of the Royal Horticultural Society on May 17, when flowers were exhibited by C.G. van Tubergen, of Haarlem, Holland, to whom we are indebted for the species from which our illustration has been prepared». Wilford (2006) separated T. tubergeniana from T. ingens Hoog (1902: 14) as an accepted species. Zonneveld (2009) placed T. ingens as a synonym of T. tubergeniana. However, Christenhusz et al. (2013) treated T. tubergeniana as a synonym of T. ingens. These two species show significant differences in bulb morphology and ecological characteristics (Tojibaev & Beshko 2014) and should be treated separate as accepted species (Fig. 2A).

2.5. Tulipa ferganica Vved. in Byull. Sredne-Aziatsk. Gosud. Univ. 21: 148 (1935). Type:— KYRGYZSTAN. Grown in the experimental plot of the Botanical Garden of Central Asian University from bulbs brought by Z.P. Botschantzeva from upper reaches of the river Kugart, above the confluence with Aubek, 23 August 1933, Vvedensky 592 (holotype TASH000508!). Description:—Bulb ovoid, 1.5–3.0 cm thick; tunic black to black-brown, tough coriaceous, inside densely adpressed lanate-hairy at the base and at apex; stem (5) 10–40 cm long, the upper part of stem and peduncle pubescent; leaves 3–4(5), commonly spreading, approximate, rarely scattered, more or less pubescent, ciliate, more or less curled, rather rapidly decreasing in size up the stem, not exceeding the flower; basal leaf lanceolate or oblong, 1.5–4.0 cm broad; flowers 1(2), initially cup-shaped, opening to a wide star; perigone segments 2.5–5.0(6.5) cm long, yellow, violet or red tinged on the outside (especially outer tepals); outer segments oblong to oblong-rhomboidal, gradually acuminate or acute with a pubescent tip; inner segments oblong, acuminate with a slightly pubescent or glabrous tip; stamens two or three times shorter than the perigone; filaments glabrous, bright yellow; anthers bright yellow, oblong, dilated at the base, slightly longer than filaments; ovary yellowish green, slightly shorter than stamens, with subsessile stigma; capsule 1.5–2.0 cm broad, 2.5–4.0 cm long (Fig. 5C). General distribution:—Fergana, Chatkal and Alay Ranges (Kyrgyzstan, Uzbekistan). Distribution in Uzbekistan:—I-2 Fergana district (I-2-a South Chatkal region), I-3 Fergana-Alay district (I-3-b Eastern Alay region). Phenology:—Flowering: April–May; fruiting: June–July. Ecology:—Fine earth, gravelly and stony slopes in lower and middle mountain zone, rarely in foothills, 700–3000 m a.s.l. Etymology:—The bulbs of this species have been collected by Z.P. Botschantzeva from the upper reaches of the river Kugart on the Fergana Range, one of the huge mountain ranges surrounding the Fergana Valley. Perhaps, Vvedensky named the species Tulipa ferganica for this reason. Note:—According to J.J. de Groot’s communication, based on long-term observations in his living collection, at least two forms of T. ferganica Vvedensky (1935: 148) can be distinguished: 1) early flowering plants of relatively stocky habit that have been collected from the western part of the species range (Naryn, Osh); 2) late flowering and relatively tall plants from the eastern areas (Kugart). Thus, T. ferganica may be a group of very similar species, and further comparative studies are required.

Description:—Bulb ovoid, 2–5 cm thick; tunic blackish-brown, coriaceous, inside densely covered with long silky hairs, especially at the base and at the top; stem 15–35(50) cm long, robust, glabrous, the upper part of stem and peduncle pubescent; leaves 3–4(6), large, deflexed, scattered, slightly undulate, glaucous or green, pubescent, ciliate at margins, not exceeding the flower; lower leaf oblong to elliptic, 3–15 cm broad, situated on the soil level; upper leaves progressively decreasing in size; flower solitary, large, widely cup-shaped; perigone segments bright red, 4.5–12.5 cm long, commonly obtuse with a very short pubescent tip; the basal blotch usually 3-pointed, sharp or blurred, black, dirty violet or olive-coloured, more or less widely margined with yellow (rarely without yellow margin), sometimes yellow throughout; outer segments oblong-elliptic to oblong; inner segments obovate to oblong; stamens one third to two-fifths the length of perigone; filaments glabrous, black, sometimes yellow; anthers violet, twice the length of the filaments; pollen purple-brown or yellow; ovary green, slightly shorter than anthers, with sessile stigma; capsule 2.5–3.0 cm broad, 5–7 cm long. General distribution:—Western Pamir-Alay (Tajikistan, Uzbekistan), Afghanistan (probably, introduced). Distribution in Uzbekistan:—I-5 Kuhistan district (I-5-c Urgut region). Phenology:—Flowering: April–May; fruiting: May–June. Ecology:—Clayey, stony and gravelly slopes, rock ledges in middle mountain zone, 1500–2600 m a.s.l. Etymology:—The species was named after Prof. M. Foster, who gardened at Shelford, near Cambridge (Wilford 2006). Note:—It is one of the most beautiful tulip species introduced in Europe from Uzbekistan. Austrian (or German) entomologist J. Haberhauer collected bulbs of this species from the Emirate of Bukhara (the exact location is unknown) during the Central Asian expedition of 1861–1862 and sent these bulbs to the famous European gardener C.G. van Tubergen. 26 May 1906, after several decades of cultivation in Europe, Irwing (1906) described this species in Garden`s Chronicle. However, the scientific name T. fosteriana has been used for the first time one year before, in 1905, when this plant won an Award of Merit from the Royal Horticulture Society. Irwing predicted a great prospect of this tulip in ornamental gardening and noted in Garden`s Chronicle that «the flowers are of very large size, and of a rich, intense, glowing, crimson colour, with a darker blotch at the base of the segments; of robust habit, and as easily grown as many of the other brilliant species from this part of Eastern Turkestan, T. fosteriana will probably become a favorite plant when more common» (Fig. 3C).

2.9. Tulipa hissarica Popov & Vved. in Byull. Sredne-Aziatsk. Gosud. Univ. 21: 149. (1935). Type:— TAJIKISTAN. Hissar Mountains, pass Mura, 14 April 1915, Popov 10634 (holotype TASH!). Description:—Bulb oblong-ovoid, 1.0–1.5(2.0) cm thick; tunic brown or grayish, papery, prolonged, inside at the top lined with adpressed hairs; stem 4–12 cm long, glabrous, bluish-green, hidden in the rosette of leaves at the beginning of flowering and later elongating; leaves (2–3)4–5, approximate, nearly verticillate, exceeding the flower, spreading, curled, glabrous, smooth or slightly ciliate at margins, linear or almost lorate, 0.5–1.0(2.0) cm broad; flower solitary, star-shaped, with a pleasant saffron-like scent; perigone segments yellowish, without basal blotch, 2–3 cm long, acute, glabrous; outer segments lanceolate, greenish and violet-tinged on the back, two-thirds as broad as and slightly longer than the inner segments, the edges of the upper half often notched; inner segments oblong, often obtuse, gradually tapering to the base and sometimes notched at edges; stamens one and a half to two times shorter than the perigone; filaments glabrous, yellow, tapering from the base to the apex; anthers yellow or orange, linear-oblong, up to 9 mm long; ovary slightly shorter than stamens, green, with a very long style; stigma light yellow; capsule straw-coloured or purplish, cylindrical with purple-tinged ribs. General distribution:—Hissar Range (Tajikistan, Uzbekistan). Distribution in Uzbekistan:—I-7 Hissar-Darvaz district (I-7-a Sangardak-Tupalang region). Phenology:—Flowering: May–June, fruiting: June–July. Ecology:—Stony slopes in middle and upper mountain zone, 1300–3500 m a.s.l. Etymology:—The species took its name from the Hissar Range (Pamir-Alay), from which this tulip is known. Note:—This species (as well as the next species, Tulipa korshinskyi), is widespread mainly in Tajikistan and known only from solitary locations on the highlands of Hissar Range, near the border with Uzbekistan. Previously, this tulip has been reported as endemic to Tajikistan (Vvedensky 1963, Vvedensky & Kovalevskaja 1971). Specimens examined:— UZBEKISTAN: Hissar-Darvaz, Sangardak-Tupalang region, Hissar Range, Obi-Zarang river basin, juniper forest, 19 May 1948, Bondarenko 617 (TASH!); Obi-Zarang river basin, surroundings of Aspi-Rectan, 21 May 1948, Chevrenidi 660 (TASH!); Bukhara, Gissar, Gissar range, Khshir pass, 6 June 1896, Lipsky s.n.

5.8. Tulipa orithyioides Vved. in Byull. Sredne-Aziatsk. Gosud. Univ. 21. 150 (1935). Type:— UZBEKISTAN. Tschulbair, 30 June 1929, Vvedensky 423 (holotype TASH000514!). Description:—Bulb ovoid, (1.0)1.5–2.0 cm thick; tunic almost papery, brownish-gray, with arachnoid hairs which protrude at the apex; stem 7–10 cm long, glabrous; leaves 2(3), approximate to subopposite, spreading, curled, glabrous, smooth, significantly exceeding the flower; lower leaf linear-lanceolate, broader, 1.0– 1.5 cm broad; flower solitary, star-shaped; perigone segments white, yellow at base, 18–24 mm long, acute; outer segments dingy violet outside, lanceolate, glabrous; inner segments gradually narrowed into a claw, oblanceolate, ciliate at base, slightly shorter; stamens half the length of perigone; filaments yellow, hairy at the base, long-ciliate below; anthers greyish-yellow, linear-oblong, 5–6 mm long, with a very short cusp; ovary as long as stamens, with a very long style; capsule oblong, ca. 1.5 cm broad, 2–3 cm long, long-beaked. General distribution:—Hissar Range (Tajikistan, Uzbekistan). Distribution in Uzbekistan:—I-6 Western Hissar district (II-6-c Baysun region), I-7 Hissar-Darvaz district (I-7-a Sangardak-Tupalang region). Phenology:—Flowering: June; fruiting: July. Ecology:—Gravelly and stony slopes, in middle and upper mountain zone, 1800–3000 m a.s.l. Etymology:—Species epithet “ orithyioides ” means “similar to Orithyia ”. Wilford (2006) noted that the name of this species, described by Vvedensky in 1935, is connected with its very long style which is one of the features of the section Orithyia. Note:— Vvedensky (1935) placed T. orithyioides in T. sect. Eriostemones. The species is similar to T. turkestanica but differs from its dwarf habitat and crisp leaves (Everett et al. 2013). Wilford’s (2006) and Everett`s (2013) indications of the growing of this species in the Zarafshan ridge is not true. Specimens examined:— UZBEKISTAN: Surkhandarya, Hissar Range, River basin Obi-zarang, on the way from the village Samarkand to the upper reaches of the river Obi-zarang, 21 May 1948, S.Kh. Chevrenidi 678 (TASH!); Baysun, Khodzha-Gurgurata mountains, Chakmoksay, 25 June 2012, O. Turginov s.n.

(TASH!); Hissar Range, Chulbair, watershed between the rivers, Sina and Malyangur, in juniper forests among thickets of Ungernia victoris, 27 May 1960, Korotkova 8139 (TASH!). The species of the section in the study area are widespread across different habitats (mainly in plains – T. sogdiana, T. buhseana and T. biflora; in middle mountains – T. bifloriformis, T. turkestanica; in alpines – T. dasystemon, T. dasystemonoides, T. orithyioides) (Fig. 13). The decreasing of the populations can be observed with T. sogdiana due to irregular pasture in Kyzyl-Kum deserts. Appearance of new locations of T. buhseana in the west of the area (Karakalpakstan) is explained by the geobotanical investigations by the scientists of the Institute of Botany (https:// botany.uz/en/geobotanika_laboratoriyasi/)., Published as part of Tojibaev, Komiljon, Dekhkonov, Davron, Ergashov, Ibrokhimjon, Sun, Hang, Deng, Tao & Yusupov, Ziyoviddin, 2022, The synopsis of the genus Tulipa (Liliaceae) in Uzbekistan, pp. 163-214 in Phytotaxa 573 (2) on pages 208-209, DOI: 10.11646/phytotaxa.573.2.2, http://zenodo.org/record/7349887, {"references":["Wilford, R.

3.3. Tulipa micheliana Hoog in Gard. Chron. III, 31: 350. (1902). Type:—figure 120, Gard. Chron. Ser.3, 31: 353 (1902) [lectotype designated by Wilford, 2013: 63]. Description:—Bulb ovoid, 2–3 cm thick; tunic coriaceous, blackish-brown, often prolonged, the inner surface hairy, more densely at the apex and at base; stem 15–40 cm long, the upper part of stem and peduncle pubescent; leaves 4 or 5, deflexed, more or less scattered, glaucous, with violet often interrupted stripes or without stripes, more or less pubescent, ciliate, undulate, gradually decreasing in size up the stem, usually not exceeding the flower; basal leaf linear-lanceolate to oblong, 2–6 cm broad; flower solitary; perigone segments red to crimson-red, equal or the outer slightly longer, 2.5–10 cm long, rather abruptly acuminate to a pubescent tip, with a narrow triangular, long, acute or 3- pointed, yellow-margined (rarely without yellow margin) black blotch, 1/3–1/2 the length of the tepal; outer segments slightly pubescent on the black, broadly rhomboidal to oblong-rhomboidal, rarely oblong-lanceolate; inner segments obtriangular or oblong, rarely oblong-lanceolate; stamens one third to two-fifths the length of perigone segments; filaments glabrous, black, at the base yellowish or red, flattened, triangular; anthers commonly violet, twice the length of filaments; pollen yellow; ovary slightly shorter than stamens, green, with sessile stigma; capsule cylindrical, 1.5–2.5 cm broad, 3–6 cm long, greenish-buff. General distribution:—Pamir-Alay, Kopetdag (Afghanistan, Iran, Tajikistan, Turkmenistan, Uzbekistan). Distribution in Uzbekistan:—I-4 Nuratau district (I-4-a Nuratau region; I-4-b Aktau region; I-4-c Nuratau Relict Mountains), I-5 Kuhistan district (I-5-a North Turkestan region; I-5-a Malguzar region; I-5-d Zirabulak-Ziadin region), I-6 Western Hissar district (I-6-a Kashkadarya region; I-6-c Baysun region; I-6-b Tarkapchigay region; I-6-d Kuhitang region). Phenology:—Flowering: April–May; fruiting: May–June. Ecology:—Piedmont plains, clayely and stony slopes in foothills, lower and middle mountain zone, 350–1800 m a.s.l. Etymology:—The species is named after M. Micheli (1844–1902), a Swiss botanist. Note:—The species was described in 1902 by T. Hoog on specimens collected in 1900 by German botanist P. Sintenis near Ashkhabad (Turkmenistan). Wilford (2013) treated this tulip as Tulipa undulatifolia var. micheliana (Hoog) Wilford. According to J.J. de Groot’s communication, T. micheliana from the Kopet-Dag and Northern Iran have a lower amount of DNA than the plants from South-Western Pamir-Alay. It shows that under the name of T. micheliana may be a group of very similar species, and further comparative studies are required.

Distribution in Uzbekistan:—I-1 Western Tian-Shan district (I-1-d Kurama region; I-1-f Tashkent region), I-4 Nuratau district (I-4-a Nuratau region; I-4-b Aktau region; I-4-c Nuratau Relic Mountains), I-5 Kuhistan district (I-5-a North Turkestan region; I-5-b Malguzar region; I-5-d Zirabulak-Ziadin region; I-5-c Urgut region), I-6 Western Hissar district (I-6-a Kashkadarya region; I-6-b Tarkapchigay region; I-6-c Baysun region; I-6-d Kuhitang region; I-6-e Surkhan-Sherabad region). I-7 Hissar-Darvaz district (I-7-a Sangardak-Tupalang region), I-8 Panj district (I-8-a Babatag region), II-3 Kyzylkum district (II-3-a Kyzylkum region). Phenology:—Flowering: March–April (depending on elevation); fruiting: May–June. Ecology:—Gravelly and stony slopes, rocks, outcrops of variegated beds, from piedmonts up to subalpine zone, 400–2200 m a.s.l. Etymology:—The species is named after N. Korolkow (1843–1933)—general of the Russian army, the author of scientific works on beekeeping and etymology, and naturalist-amateur who studied the flora and fauna of Central Asia. He was the initiator and leader of the establishement of forest plantations on the slopes of the Zeravshan Range (Amankutan forestry). According to some sources, he invented and applied the terracing method in forestry. In city of New Margilan (Fergana Valley), thousands of garden roses and paulownia grew in his garden, which struck his British guest, L. Denmore in 1893. E. Regel described this species in 1875 on the material collected by Korolkow and Krause near town of Farish (Nuratau Range, Uzbekistan) (Fig. 5B). Note:—Two more taxa related to T. korolkowii Regel (1875: 295) have been described from Central Asia, and their taxonomical status is a subject of discussion. They are T. rosea Vvedensky (1935: 343) which grows in north Tajikistan (in the western part of Fergana Valley), and T. nitida Hoog (1902: 350) widespread in Western Pamir-Alay and South-Western Tian-Shan (in the same areas as T. korolkowii). In the «Flora of USSR» (1935) and «Flora of Uzbekistan » (1941), Vvedensky gave T. korolkowii, T. nitida and T. rosea as three geographically separated species, and reported the first of them for foothills of South-Western Tian-Shan and Northern Pamir-Alay, the second species – for Western and South-Western Pamir-Alay, and the third species – for the western part of Fergana Valley. However, he noted that the morphological differences between T. korolkowii (leaves exceeding the flower, smaller flower, black filaments, greenish ovary) and T. nitida (strongly curled leaves not exceeding the flower, larger flower pendulous in the bud, black or pink filaments, pinkish ovary) are unclear and the separation of these two species is artificial. Later, in “Conspectus Florae Asiae Mediae” (1971), T. nitida has been treated by Vvedensky & Kovalevskaja as a synonym of T. korolkowii. Based on the results of flow cytometry, Zonneveld (2009) regarded T. korolkowii and T. nitida as two distinct species and T. rosea as T. korolkowii f. rosea (Vvedensky) Zonneveld (2009: 244). Christenhusz et al. (2013) considered T. nitida and T. rosea as synonyms of T. korolkowii. According to J.J. de Groot’s personal communication, in the same conditions ex-situ, T. nitida and T. korolkowii f. rosea bloom earlier than T. korolkowii. Concerning T. korolkowii and T. nitida, our long-term surveys in natural habitats and observations in ex situ living collection of TASH and Tashkent Botanical Garden showed that such characters as more or less curled leaves, the length of stem, leaves, and tepals are variable depending on habitat and climatic conditions. Dwarf plants with strongly curled approximate leaves exceeding almost sessile flower occur on open dry stony places, while the plants growing on fine soils in relatively humid and shady places usually are more or less tall, with slightly undulate leaves not exceeding the flower. As for colour of filaments and ovary, plants with black, purple, and bicolour black-purple filaments as well as greenish and pinkish ovary can be found in the same population. As regards tulip with pink or crimson flowers which has been treated as T. rosea in above mentioned classical works, we were unable to find any materials confirming the presence of this taxon within the present-day boundaries of the Republic of Uzbekistan.

3.2. Tulipa mogoltavica Popov & Vved. in Opred. Rast. Sred. Azii 2: 318. (1971) Type:— TAJIKISTAN. Tian-Shan Occidentalis: ad declivia saxosa montium Mogoltau in angustiis fl. Schunluk, 22 April 1927, I. Granitov 483 (holotype TASH000513! isotypes: BM, H-1200899). Description:—Bulb ovoid, 2–4 cm thick; tunic more or less produced, coriaceous, blackish-brown, hairy on the inside, more densely at apex and at base; stem 10–30 cm long, the upper part of stem and peduncle pubescent; leaves 3–4, sub approximate, spreading, curled, glaucous, with violet dashes and spots, more or less pubescent, ciliate, rather gradually decreasing in size up the stem, not exceeding the flower; basal leaf oblong-lanceolate to widely oblong, 2–7 cm broad; flower solitary; perigone segments bright red, 3–10 cm long, abruptly acuminate to a short pubescent cusp, with a black yellow-margined or without yellow margin basal blotch; outer segments pubescent on the back, elliptic-rhomboidal, reflexed in the upper part, slightly shorter than the triangular-obovate more or less connivent inner segments; stamens two-fifths the length of perigone; filaments glabrous, black, flattened, triangular in section; anthers blackish-violet, twice the length of the filaments; pollen dark brown-purple; ovary slightly shorter than stamens, pale green, with subsessile stigma; capsule ca. 2 cm broad, 3–4 cm long. General distribution:—South-western Tian-Shan (Tajikistan, Uzbekistan). Distribution in Uzbekistan:—I-1 the Western Tian- Shan district (I-1-d Kurama region). Phenology:—Flowering: April–May; fruiting: May–June. Ecology:—Clayely and stony slopes in foothills and lower mountain zone, 500–1600 m a.s.l. Etymology:—The species is named after the range Mogoltau (south-west spurs of Tian-Shan, Tajikistan), where it has been discovered. Note:—All known records of this tulip in Uzbekistan are based on the herbarium collections of the XX Century. The taxonomical status of Tulipa mogoltavica is questionable because the morphological differences between T. mogoltavica and T. greigii are not clear, but these taxa are more or less isolated geographically and plants of T. mogoltavica are smaller than T. greigii. Many authors (Hall 1940, Wilford 2006, Christenhusz et al. 2013), considered this tulip as a synonym of Tulipa greigii. However, Zonneveld (2009), based on the study of original materials from locus classicus (i.e. Mogoltau Range), showed differences in their amount of nuclear DNA, between these two species. A survey of populations and further comparative studies of T. mogoltavica and T. greigii are strongly required.

Ecology:—Sandy, clayey and stony deserts, relic mountains, up to 500 m a.s.l. Etymology:—This tulip has been named after the Russian botanist Borszczow (1833–1878), a specialist for plant taxonomy, physiology, and anatomy, who collected this plant for the first time in 1857 from the Aralo-Caspian region. Note:—Previously, this species has been reported as endemic of Kazakhstan widespread in western Betpakdala, Aral deserts, northern Kyzylkum, and the lower reaches of Sarysu River (Vvedensky 1935, 1941, Vvedensky & Kovalevskaja 1971, Ivashchenko 2005). It was not included in the checklist of the flora of Uzbekistan. In 2002, it has been collected from Uzbekistan for the first time (from the western part of Hungry Steppe near the borders with KyzylKum desert and Kazakhstan (Beshko s.n., TASH). Specimens collected from the neighboring areas of Kazakhstan are kept at TASH. Later, several new populations have been found in the Uzbekistan part of Kyzyl-Kum, including relic mountains Muruntau and Kuldjuktau (Abduraimov et al. 2018). At present, seven locations of this species are known in Uzbekistan (3–in the western part of Hungry Steppe and the eastern edge of Kyzylkum, 4–in relic mountains). The populations of the Hungry Steppe (Mirza-Chul) and eastern Kyzyl-Kum are comprised of a yellow form, whereas a red form of this tulip occurs in the insular low mountains Muruntau.

3.5. Tulipa butkovii Botschantz. in Bot. Mater. Gerb. Inst. Bot. Zool. Akad. Nauk Uzbeksk. S.S.R. 16: 8. (1961). Type:— UZBEKISTAN. Grown in the Botanical Garden of the Academy of Sciences of Uzbek SSR from bulbs collected by Z. P. Botschantzeva in 1959 on steep south-western slopes (almost screes) of the mountain Smaller Chimgan, Botschantzeva 3754 (holotype TASH000505!). Description:—Bulb ovoid 2–3 cm thick; tunic brown, papery, slightly elongate, on the inside lined with short, adpressed golden hairs, more densely at the apex and at base; stem (10) 15–30 cm long, brownish-green, glaucous and pubescent; leaves 3–4, approximate, reflexed, sometimes exceeding the flower, more or less curled, glaucous, pubescent, ciliate at margins of a lighter shade; basal leaf broadly lanceolate, 2.0– 4.5 cm width, its basal partis below soil level; upper leaf narrow lanceolate; flower solitary, widely campanulate, opening to a wide cup or wide star; perigone segments 3.5– 5.5(6) cm long, crimson-red or purple-red to brick-red, glaucous and purple-tinged on the back, with small, diffuse, brown-purple basal blotch or without distinct blotch (tepals blurred brownish or greenish-yellow at the base); inner segments oblong or narrowly ovate, rounded at the top and more or less apiculate, with a pubescent tip; outer segments narrowly oblong or lanceolate, obtuse or rounded at the top; stamens 2.0–2.5 times shorter than the perigone; filaments red, brownish or purple, equal or exceeding the ovary, thin, dilated towards the base; anthers yellow or purple, shorter, equal or almost twice as long as the filaments, gradually dehiscing from the top to base, but not twisted; pollen yellow or purple; ovary bottle-shaped, cream-coloured or pale green, purple-tinged along the ribs and below stigma; capsule oblong-ovate, broader at the base than near the style, pale grey with a pattern of maroon spots and stripes, with a rather long beak (Fig. 8C). General distribution:—Endemic to the western part of Chatkal Range (Uzbekistan). Distribution in Uzbekistan:—I-1 the Western Tian-Shan district (1-b Western Chatkal region). Phenology:—Flowering: April–May; fruiting: May–June. Ecology:—Fine earth, gravelly and stony slopes, screes and rocks, in middle mountain zone, 1300–2200 m a.s.l. Etymology:—This species is named after A. Butkov (1911–1981), a well-known plant taxonomist and geobotanist, who worked at the Institute of Botany of the Academy of Sciences of Uzbekistan and collected this tulip species from different areas of Chatkal Range in 1955–1956. Note:—The taxonomical status of T. butkovii is still uncertain. The main distinctive character of T. butkovii is red filaments. Van Raamsdonk et al. (1997) treated this species as synonym of T. albertii Regel. Zonneveld (2009), Christenhusz et al. (2013) and Everett (2013) restored T. butkovii as a separate species of sect. Vinistriatae. Specimens examined:— UZBEKISTAN: Western Tian-Shan district, Western Chatkal region, Chatkal Range, Chatkal Nature Reserve, Greater Maydantal, gravelly slopes, August 1955, Butkov s.n. (TASH!); Chatkal Nature Reserve, Smaller Maydantal, among the rocks, August 1955, Butkov s.n. (TASH!); Akbulak Valley, Karasay, gravelly slopes, 1820–2000 m, 1956, Butkov s.n. (TASH!); Akbulak valley, at the confluence with the Serkelisay, gravelly slopes, 1956, Butkov s.n. (TASH!). It has known that species of the section possess ornamental character which led to overexploitation of the species. For example, T. vvedenskyi (in Kurama range) and T. greigii (Chatkal range) have been selling in Uzbekistan.After 1970 populations of T. mogoltavica decreased considerable and populations of T. micheliana distributed in transboundary regions with Tajikistan are completely extincted (Fig. 9)., Published as part of Tojibaev, Komiljon, Dekhkonov, Davron, Ergashov, Ibrokhimjon, Sun, Hang, Deng, Tao & Yusupov, Ziyoviddin, 2022, The synopsis of the genus Tulipa (Liliaceae) in Uzbekistan, pp. 163-214 in Phytotaxa 573 (2) on pages 191-192, DOI: 10.11646/phytotaxa.573.2.2, http://zenodo.org/record/7349887, {"references":["Van Raamsdonk, L.

5.2. Tulipa biflora Pall. in Reise Russ. Reich. 3(2): App. 727 (1776). Type:— RUSSIA. Habitat ad Wolgam locis desertis maxime argillosis, “Deserta Caspica”, Fischer sn. (holotype B-W-06559-010; syntypes BM 000528948! and M; lectotype designated by Eker et al. 2014). Description:—Bulb ovoid, 1.5–2.0 cm thick; tunic brown or reddish-brown, papery, inside covered with thin arachnoid hairs, woolly at apex; stem 10–20 cm long, the stem and peduncle glabrous; leaves mostly 2, scattered, deflexed, very rarely spreading, glabrous, smooth, linear, green and slightly glaucous; lower leaf broader, 3–7(10) mm broad, slightly exceeding the flowers; flowers 1 or 2 (up to 6), star-shaped; perigone segments white, yellow at base, 13–25 mm long, acute; outer segments lanceolate, dingy violet outside, bearded at base, about half as broad as the inner; inner segments oblong to oblong-ovate, acuminate, gradually tapering into a rather long claw, bearded at base, ciliate; stamens half the length of perigone; filaments yellow, bearded at base; anthers oblong, 2–3 mm long, yellow, with a very short point; ovary scarcely shorter than stamens, short-styled; capsule short beaked, 8–13 mm in diameter, about as long as or slightly longer than broad. General distribution:— Kazakhstan, Uzbekistan, Afghanistan, China (northern part), the south of Russia, Transcaucasia, Crimea, the north of Iran. Distribution in Uzbekistan:—II-8 Ustyurt district (II-8-a North Ustyurt region). Phenology:—Flowering: April; fruiting: May. Ecology:—Saline deserts, clayey cliffs, in plains, up to 100 m a.s.l. Etymology:—Species epithet “ biflora ” means “two-flowered”. Note:— Tulipa biflora is a very variable species with a wide range, differing greatly in size (Everett 2013). In the understanding of the range and geographical distribution of this species, we follow Vvedensky (1935) and Vvedensky & Kovalevskaja (1971) who regarded T. biflora s.s., while Christenhusz et al. (2013) treated T. sogdiana, T. buhseana Boissier (1859: 98), T. binutans Vvedensky (1952: 33), and several other species as synonyms of T. biflora. The species is widespread in the northern part of Central Asian deserts, and does not occur in Kyzylkum and Karakum deserts. Zonneveld (2009) reported that all accessions of T. biflora have a rather narrow range of variation in the nuclear DNA values, and differing mainly in the number and size of the flowers. Nevertheless, he admitted the possibility of the presence of new, undiscovered species from the affinity of T. biflora in Central Asia. Later, Perezhogin (2013) described two new species from northern Kazakhstan [T. auliekolica Perezhogin (2014: 145) and T. turgaica Perezhogin (2014: 145)]. In addition, Everett (2013) reported the yellow form of this species from Afghanistan. Specimens examined:— UZBEKISTAN: Ustyurt district, North Ustyurt region, eastern cliff of Ustyurt plateau, 5 km north of the descent Kassarma, west side of the nameless spring, 3 th terrace, 23 May 1970, Sarybaev 5 (TASH)., Published as part of Tojibaev, Komiljon, Dekhkonov, Davron, Ergashov, Ibrokhimjon, Sun, Hang, Deng, Tao & Yusupov, Ziyoviddin, 2022, The synopsis of the genus Tulipa (Liliaceae) in Uzbekistan, pp. 163-214 in Phytotaxa 573 (2) on pages 200-201, DOI: 10.11646/phytotaxa.573.2.2, http://zenodo.org/record/7349887, {"references":["Eker, I., Babac, M.

2.8. Tulipa talassica Lazkov in Turczaninowia 14(3): 11. (2011). Type:— KYRGYZSTAN. Jugi Kirgisici declivium generale australe, praemontia adversus urbem Talas, declivitates lapidosae, 27 April 2011, G. Lazkov (holotype LE!; isotypes ALTB, FRU, MW!). Description:—Bulb ovoid, 1.5–2.5 cm thick; tunic thin coriaceous, dark brown to black-brown, prolonged (sometimes almost to the soil surface), usually more or less hairy inside; stem 5–20 cm long, glabrous, erect in buds; leaves 3, more or less scattered, reflexed, glaucous-green, glabrous, ciliate at edges, undulate, lanceolate, 5–20 cm long; flowers solitary; perigone segments yellow, 2.0–3.5(4) cm long; outer segments oblong-lanceolate, on the outside more or less intensively red-tinged, yellow-margined; inner segments obovate, oblong-obovate or almost rhomboidal; stamens 2.5–3.0 times shorter than perigone, filaments glabrous, yellow; anthers yellow, almost equal with the filaments; stigma sessile or subsessile (Fig. 6C). General distribution:—Tian-Shan (Kyrgyzstan, Uzbekistan). Distribution in Uzbekistan:—I-1 Western Tian-Shan district (I-1-e Chorkesar region). Phenology:—Flowering: April; fruiting: June. Ecology:—Stony slopes in foothills and lower mountain zone, 800–1300 m a.s.l. Etymology:—The name of this tulip is associated with the town Talas (Kyrgyzstan), from surroundings of which the species has been found for the first time. Note:—At first sight, T. talassica looks the same as T. intermedia. But in cultivation, growing under the same circumstances they show their real character, which shows that they are not closely related. T. intermedia is clearly a member of the Korolkowii group of tulips. In the wild it grows on acid soils, granite etc. Whereas T. talassica belongs to the Kolpakovskiana group of tulips, but differ from T. kolpakovskiana and close relatives, that it grows on chalk soil, not that it likes chalk, but it found a way to managed it as shown on the powdered stem on the photo that I took on the type place. In cultivation T. talassica has inner tepals of the same size as the outers or slightly smaller, and has no basal spot, the outer tepals have pale reddish outside. T. intermedia has bigger inner tepals as the outers and a clearly visable small basal spot. Both species differ in in their genetical parts also.

2.10. Tulipa korshinskyi Vved. in Byull. Sredne-Aziatsk. Gosud. Univ. 21: 149. (1935). Type:— TAJIKISTAN. Darvaz, 17 April 1897, Korshinsky 1713 (4928) (holotype LE!). Description:—Bulb ovoid, 1.5–2.0(3) cm thick; tunic coriaceous, dark brown, almost black, the inner surface lined at the apex and at the base with adpressed hairs; stem (5) 10–20 cm long, mostly underground at the beginning of flowering and later elongating, the stem and peduncle glabrous; leaves (2–3)4(5), approximate, nearly verticillate, exceeding the flower, strongly spreading or sometimes deflexed, glabrous, curled, commonly exceeding the flower; basal leaf lanceolate, 1.5–3.0 cm broad, the other reduced in size; flower solitary, sometimes 2, stellate with a thin peduncle; perigone segments inside white with yellow basal blotch, 1.5–4.0 cm long; outer segments linear-lanceolate, violettinged on the back, up to half as long again as the oblanceolate-rhomboidal to obovate-rhomboidal inner segments; stamens half the length of perigone; filaments yellow with an orange tip, glabrous, with nearly parallel margins, linear-oblong, abruptly narrowed at apex; anthers bright yellow, the yellow connective protruding above the apex; ovary shorter than anthers; style long, up to half as long as ovary; stigma light coloured; capsule 4 cm long, ellipsoid, acuminate at top and at base. General distribution:—Pamir-Alay (Tajikistan, Uzbekistan). Distribution in Uzbekistan:—I-6 Western Hissar district (I-6-a Kashkadarya region). Phenology:—Flowering: March–April; fruiting: May–June. Ecology:—Stony slopes in middle and upper mountain zone, 1300–3500 m a.s.l. Etymology:—The species is named after academician S. Korshinsky (1861–1900), Russian botanist and geneticistevolutionist, one of the founders of phytocenology, full member of the St. Petersburg Academy of Sciences; 45 species and one genus of plants have been named after him. Note:— T. korshinskyi is one of the species recently recorded for Uzbekistan for the first time based on herbarium specimens collected in the middle of XX Century near the border with Tajikistan Previously, it has been reported as endemic to Tajikistan (Vvedensky 1963, Vvedensky & Kovalevskaja 1971). Botschantzeva (1962) and Zonneveld (2009) considered this tulip as a separate species of sect. Kolpakowkianae. According to Christenhusz et al. (2013), it is synonym of T. anisophylla Vvedensky (1935: 147). Further studies are strongly required. Specimens examined:— UZBEKISTAN: Western Hissar district, Kashkadarya region, Hissar Range, the upper part of the Aksu river, above the village Suvtushar, 16 June 1957, Adylov 518 (TASH!). High decreasing rate after 1970 is visible with species distributed in the hotspots where impact of anthropogenic factors (habitat loss, fragmentation, overgrazing) is high. Especially, T. lehmanniana from the central part of the study area is under high anthropogenic impact where overgrazing and fragmentation of populations are increasing year by year. The situation can be observed with T. korolkowii and the recently described species (T. scharipovii, T. intermedia) in Chap badlands (Pap district, Namangan region). Single individuals of T. hissarica and T. korshinskyi can be found in the transboundary region with Tajikistan. The appearance of the populations in the north of Fergana Valley is explained as an increase of botanical investigations which provided descriptions of 3 new tulip species (T. talassica, T. intermedia and T. scharipovii) (Fig. 7)., Published as part of Tojibaev, Komiljon, Dekhkonov, Davron, Ergashov, Ibrokhimjon, Sun, Hang, Deng, Tao & Yusupov, Ziyoviddin, 2022, The synopsis of the genus Tulipa (Liliaceae) in Uzbekistan, pp. 163-214 in Phytotaxa 573 (2) on pages 185-186, DOI: 10.11646/phytotaxa.573.2.2, http://zenodo.org/record/7349887, {"references":["Vvedensky, A.

Phenology:—Flowering: April; fruiting: May. Ecology:—Red clays hills and in grass at the foot of these hills. It grows between short grasses at a depth of about 20 cm, 400–600 m. Etymology:—The species is named after ancient Persian kingdom of Bactria which covered the upper part of the Amu Darya river basin including distribution area of this species (Fig. 2B). Note:—In the first description of the species, the authors assigned it to the T. sect. Tulipanum De Reboul (1847: 60). The species can be recognized in the wild by its long cusps on all the tepals, in contrast with other red flowering species in the same growing area that have only long cusps on the outer tepals. It differs from T. tubergeniana also by the longer stem with long arched and straight leaves; from T. lanata Regel (1884: 647) by its slenderer habit and the covering of the bulb tunic; T. lanata has a thick layer of shaggy long hairs whereas T. bactriana has a woolly coating (de Groot & Tojibaev 2020). In this synopsis, we assign the species to the sect. Lanatae as well as T. tubergeniana. Specimens examined:—Currently, the species is represented only by the type specimen., Published as part of Tojibaev, Komiljon, Dekhkonov, Davron, Ergashov, Ibrokhimjon, Sun, Hang, Deng, Tao & Yusupov, Ziyoviddin, 2022, The synopsis of the genus Tulipa (Liliaceae) in Uzbekistan, pp. 163-214 in Phytotaxa 573 (2) on pages 167-168, DOI: 10.11646/phytotaxa.573.2.2, http://zenodo.org/record/7349887, {"references":["De Reboul, E.

5.7. Tulipa dasystemonoides Vved. in Byull. Sredne-Aziatsk. Gosud. Univ. 21: 147. (1935). Type:— KAZAKHSTAN. Altai Talac, 11 June 1909, Minkwitz 1365 (holotype LE!). Description:—Bulb ovoid, 1.0–1.5(2.0) cm thick; tunic blackish-brown, sub-coriaceous, the inner surface densely covered with woolly hairs at the apex; stem 7–15 cm long, often red-tinged, the stem and peduncle densely pubescent; leaves 2, more or less approximate, commonly spreading, glabrous, smooth, linear, significantly exceeding the flower; lower leaf broader, 6–12 mm broad; flowers 1(2), opens to a wide creamy-white star with a large yellow blotch (rarely yellow without blotch); perigone segments 15–25 mm long, acuminate; outer segments lanceolate, dingy violet outside, glabrous, two-thirds as broad as the inner; inner segments oblong, gradually tapering into a claw, more or less ciliate at base; filaments yellow, thread-like, dilated and bearded at base, half the length of perigone; anthers linearoblong, yellow, 4–5 mm long, with a very short cusp; ovary pale green, about half the length of the stamens, with a long style and cream-coloured overlapping stigma; capsule pale beige with darker angles, rounded, up to 3.5×2.0 cm, with a short beak. General distribution:—Tian-Shan, Pamir-Alay (Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan). Distribution in Uzbekistan:—I-1 Western Tian-Shan district (I-1-a Ugam-Pskem region; I-1-b Western Chatkal region; I-1-d Kurama region), I-3 Fergana-Alay district (I-3-b Eastern Alay region), I-5 Kuhistan district (I-1-a North Turkestan region). Phenology:—Flowering: April–July; fruiting: July–August. Ecology:—Fine earth, gravelly and stony slopes, in upper mountain zone, 2500–3500 m a.s.l. Etymology:—Species epithet “ dasystemonoides ” means “similar to T. dasystemon ” (hairy stamen). Note:— Van Raamsdonk et al. (1997) and Christenhusz et al. (2013) consider the species as synonym to T. dasystemon. According to Zonneveld (2009), these two species have different amount of nuclear DNA, 57.7 pg for T. dasystemoniodes and 51.5 pg for T. dasystemon. Morphologically, these species differ well from each other with bulb tunics (Vvedensky 1935, Hall 1940, Botschantzeva 1962). Tulipa dasystemonoides sometimes has two flowers per stem, while T. dasystemon always has a single flower (Vvedensky 1935, Hall 1940, Botschantzeva 1962). There is a similarity between Т. dasystemon and T. dasystemonoides, but T. dasystemonoides possesses densely wooly tunic and usually creamy-white flower (Everett et al. 2013). They also show differences in bulb characteristics.

1.7. Tulipa affinis Botschantz. in Bot. Mater. Gerb. Inst. Bot. Zool. Akad. Nauk Uzbeksk. S.S.R. 16: 6. (1961). Type:— KYRGYZSTAN.Turkestan Range near the village Churbek in juniper belt on fine earth among huge stones, 1956, V.P. Botschantzev 2190 (holotype TASH000497). Description:—Bulb elongated-ovoid, 2–4 cm thick; tunic brown or dark brown, thinly subcoriaceous, often slightly prolonged, inside sparsely lined with straight, long, adpressed, golden hairs (more densely at the base and at the top); stem 15–35(–40) cm long, green or glaucous, the upper part of stem and peduncle pubescent; leaves 3(–4– 5), scattered, glaucous, pubescent, ciliate, more or less undulate; lower leaf widely lanceolate, oblong-lanceolate or oblong, 3–5(–6) cm wide, situated above the soil level; upper leaves lanceolate, progressively decreasing in size; flower solitary, scentless, large, cyathiform, widely campanulate or widely cup-shaped, nearly tetrahedral at the base; perigone segments bright red, 5–7(–11) cm long, acuminate, with a pubescent tip; the basal blotch relatively small, black with narrow yellow margin (sometimes without yellow margin), sinuate, dentate or truncate; outer segments oblong to oblong-rhomboidal, slightly longer than the obovate-oblong inner segments; stamens one third to two-fifths the length of perigone; filaments glabrous, black, flattened, triangular, the constricted part below the anthers usually white; anthers black-violet, twice the length of filaments; pollen purple-black; ovary narrow, long, pale green, often purple tinged; stigma large, sessile, cream coloured; capsule oblong, ca. 2 cm broad, 3–6 cm long, with a long (up to 1.2 cm) beak at the apex. General distribution:—North-western Pamir-Alay (Kyrgyzstan, Tajikistan and Uzbekistan). Distribution in Uzbekistan:—I-4 Nuratau district (I-4-a Nuratau region; I-4-b Aktau region; I-4-c Nuratau Relic Mountains), I-5 Kuhistan district (I-5-a North Turkestan region; I-5-b Malguzar region). Phenology:—Flowering: April–May; fruiting: May–June. Ecology:—Clayey, stony and gravelly slopes, rock ledges in lower and middle mountain zone, sometimes in foothills, 800–2500 m a.s.l. Etymology:—In protologue, Z.P. Botschantzeva emphasized the affinity of this species with Tulipa fosteriana. Note:—The species has been described on plants grown from bulbs collected by Z.P Botschantzeva in Turkestan Range near the village Churbek (Kyrgyzstan). In Uzbekistan, the main habitats of this tulip are located in the central part of the Nuratau Range (Beshko et al. 2013, Tojibaev & Beshko 2014). Its taxonomical status is a subject of discussion because the morphological differences between Tulipa affinis and T. fosteriana are very unclear. As noted, Botschantzeva (1961), T. affinis “…distinguishes with a more graceful habit, narrower leaves, and smaller flowers”, and its flower “...differs from all other known species by its unusual shape”. Zonneveld (2009) revealed that T. affinis has a nearly identical amount of nuclear DNA as T. fosteriana, but considered them separate species on morphological grounds etc. However, Christenhusz et al. (2013) treated T. affinis as a synonym of T. fosteriana on the grounds that morphological features noted by Botschantzeva “fit within the natural variability of T. fosteriana ». Our longterm surveys in natural habitats of both species showed that T. affinis has shorter, stocky, and more pubescent stem, narrower, more undulate and more glaucous leaves than T. fosteriana, it differs by its bulb tunics, flower shape, and shape of central blotch. A completely yellow blotch is never observed in T. affinis. Geographical ranges of these two species are separated. According to J.J. de Groot’s communication, T. affinis is shorter and blooms later than T. fosteriana in the same conditions ex-situ. Because of these facts, we consider T. affinis and T. fosteriana as two distinct, but very closely related species. Of course, further molecular genetics, morpho-anatomical and bio-ecological studies are strongly required.

The results of сomparison of populations state before and after 1970 (Fig. 4) showed the reduction of 5 species only, but in increase for T. affinis. According to our observations, the decreasing of T. tubergeniana (up to 60%) and T. fosteriana (up to 40%) populations directly depend on land use and overexploitation in the vicinities of Baysun (Surxondaryo) and Taxtakaracha pass (Zarafshan Range) respectively. Mainly overgrazing causes the reduction of populations of T. lanata, T. carinata and T. ingens. The seemingly growth rate of populations of T. affinis depended on increase of botanical expeditions and investigations in Jizzakh and Navoi regions (Beshko 2000, Batoshov 2016)., Published as part of Tojibaev, Komiljon, Dekhkonov, Davron, Ergashov, Ibrokhimjon, Sun, Hang, Deng, Tao & Yusupov, Ziyoviddin, 2022, The synopsis of the genus Tulipa (Liliaceae) in Uzbekistan, pp. 163-214 in Phytotaxa 573 (2) on pages 173-174, DOI: 10.11646/phytotaxa.573.2.2, http://zenodo.org/record/7349887, {"references":["Beshko, N.

3.1. Tulipa greigii Regel in Gartenflora 22: 290, t. 773. (1873). Type:— Illustration t. 773 in Gartenflora 22 (1873) [lectotype designated by Christenhusz et al. 2013: 312]. Description:—Bulb ovoid, 2.5–4.0 cm thick; tunic coriaceous, prolonged, blackish-brown, on the inner surface densely lined with long silky hairs especially at the apex; stem (10)20–40(50) cm long, the upper part of stem and peduncle pubescent; leaves 3–4(5), more or less approximate, deflected, more or less undulate, glaucous, with violet stripes, dashes or spots, the upper ones more or less pubescent, ciliate, rapidly decreasing in size up the stem, commonly reaching the flower; basal leaf oblong to broadly elliptic, 3.5–14.0 cm broad, glabrous; flower solitary, elegant, cupshaped or goblet-shaped, usually light red or orange-red, rarely orange, yellow, cream or motley; perigone segments at base yellow with a blurry obtuse black or dirty violet blotch (yellow form – with red spots, creamy form – with yellow center), 3–10(12) cm long, relatively thick at the base, rather abruptly cuspidate at apex, the cusp pubescent; outer segments pubescent outside (especially on the back), ovate, reflexed outwards in the upper part, broader and slightly shorter than the obovate more or less connivent inner segments; stamens one-third the length of perigone; filaments glabrous, yellow, violet or blackish; anthers yellow or violet, twice the length of filaments; pollen yellow; ovary slightly shorter than stamens, cylindrical, greenish, with sessile stigma; capsule 2–3 cm broad, 4–6 cm long (Fig. 8A). General distribution:—Tian-Shan (Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan). Distribution in Uzbekistan:—I-1 Western Tian-Shan district (I-1-a Ugam-Pskem region; I-1-b Western Chatkal region; I-1-d Kurama region; I-1-f Tashkent region). Phenology:—Flowering: April–May; fruiting: May–June. Ecology:—Clayely and stony slopes in foothills and lower mountain zone, rarely in middle mountain zone, 500– 2000(–2400) m a.s.l. Etymology:—The species is named after S. Greig (1735–1788), Russian Admiral of Scottish origin, who distinguished himself in the Chesme (1770) and Hogland (1788) battles. In 1870, on the occasion of the 200th anniversary of Peter the Great, S. Greig proposed the idea of creating the Admiralty Garden in St. Petersburg. Later he was elected as the president of the Imperial Russian Horticultural Society. The garden was led by E. Regel who described this tulip in honor of Admiral Greig. Note:—The species was described in 1873 from plants collected by famous Russian scientists Sewerzow (zoologist) and Fedtschenko (botanist) in the Karatau Mountains (present-time southern Kazakhstan). Firstly, Regel (1868) considered this tulip as a variation of the Altai tulip (Tulipa altaica var. karatavica), but later, in 1873, gave them the species rank. This species is the ornamental plant of the highest importance for selection. It is one of the most beautiful wild relatives of hundreds of cultivars of garden tulips. In the international classification, varieties of this species are combined into a separate class of “Greig’s Tulips”.
