34. Characterizing the Frequency, Morphological Gradient, and Distribution of Dioecy in Miconia (Melastomataceae).

Abstract

Dioecy has evolved many times independently within the angiosperms. The distribution, frequency of occurrence, and floral morphology of dioecious angiosperms constitute the foundations for comparative studies of dioecy, yet for many groups they are still poorly characterized. We assessed species of Miconia for the presence of a dioecious reproductive system, characterized the floral morphology for staminate and pistillate flowers, and used herbarium records to analyze patterns of distribution and elevational range. We find that dioecious Miconia represent an uncommon case of a mismatched stage of organ abortion between staminate and pistillate flowers, with functionally pistillate flower morphology being largely consistent across species and morphological expression in functionally staminate flowers varying from near-absent gynoecia to slight reductions in gynoecia. We identify 60 dioecious species and 15 putatively dioecious species within Miconia that are distributed primarily in montane habitats between 1000 and 3500 m in the Andes, parts of Central America, and the Caribbean. Our results double the last known count of dioecy in Miconia and highlight the gradient of vestigial morphology in staminate flowers. Last, we provide discussion on the significance of dioecy in relation to floral development, pollination, and ecology in Miconia. [ABSTRACT FROM AUTHOR]

Abstract

20. Meriania radula (Benth.) Triana, Trans. Linn. Soc. London 28(1): 66 (1871) [1872]. Basionym: Axinaea radula Benth., Pl. Hartw. [Bentham] 130 (1839) [1844]. Type:— ECUADOR. Loja: in Cerro San Francisco prope Loxa, no date (fl., fr.), Hartweg s.n. (lectotype, designated by Wurdack 1980: K! [barcode K 000329444]). (Figures 46–47). Axinaea purpurea Ruiz & Pav., Syst. Veg. Fl. Peruv. Chil. 1: 122 (1798). Type:— PERU. Huánuco: Muña, no date (fl., fr.), H. Ruiz & J. Pavón s.n. (lectotype, designated here: MA! [barcode MA813832]; isolectotypes: B-probably destroyed [negative at F], BM! [barcodes BM000939005, BM000939006], F! [accession nos. 842789, 844825], HAL! [barcode HAL120101], MA! [barcodes MA813830, MA813831]). Miconia incarum J.F.Macbr., Trop. Woods no. 17: 12 (1929). Type:— PERU. Huánuco: at head of canyon 6 miles south of Mito, 3000 m, 01–05 Aug 1922 (fl.), J.F. Macbride & W. Featherstone 1867 (holotype: F! [accession no. 518362]). Comments:— Meriania radula belongs to the M. radula complex which is characterized by the combination of ovate, bullate leaf blades, campanulate, deep red corollas (Fig. 47G) and stamen connectives with dorso-basal appendages perpendicular to the thecae (Fig. 46G). This complex includes M. almedae Wurdack, M. hirsuta, M. radula, M. sanguinea Wurdack and M. tetragona. Within this complex, M. radula is easily recognisable by its nodes without interpetiolar flaps and abaxial tuberculate projections on the apex of the petioles. Also, M. radula is the only species within the complex with abaxial densely setulose leaf blades, evenly covering the entire surface (Fig. 46C). The dorsal projections on the calyx in M. radula are whitish when dry and contrast with of the rest of the calyx and hypanthium. Among the Peruvian species, this feature occurs in M. penningtonii and is less conspicuous in M. hirsuta. Some specimens of M. penningtonnii have even been erroneously determined as species of the M. radula complex. However, M. radula is easily distinguishable from M. penningtonii by its terete internodes (vs. quadrangular and 4- winged) and campanulate, deep red corollas (vs. spreading, reddish-purple). Nomenclatural notes:— Axinaea purpurea and A. radula were published in 1798 and 1844, respectively. Triana (1871) [1872] considered these two species as conspecific when he proposed the combination in Meriania, and aware of the specific epithet of the former unavailable in Meriania due to the existence of M. purpurea Sw., published in 1798. Therefore, the oldest legitimate name, A. radula was used for the valid combination in Meriania (Art. 11.4 of the ICN; Turland et al. 2018). According to Art. 9.10 of the ICN (Turland et al. 2018), we must consider that Wurdack (1980) made an inadvertent lectotypification of A.radula when he wrote“ Hartweg s.n.(K, holotype) ”in his treatment of Melastomataceae for the Flora of Ecuador. Also, we chose as lectotype of A. purpurea the sheet (duplicate) housed in MA that best matches the illustration published in Ruiz & Pavón (1957, see pl. CDX), conforming with Art. 9.3 and 9.12 of the ICN (Turland et al. 2018). Distribution and phenology:— Meriania radula occurs in Ecuador and Peru, and it is recorded from Amazonas to Pasco in subparamos and elfin forests at 2590–3600 m (Fig. 30). It has been collected in flower from February to November, and in fruit in February, March, August, September and November. Specimens examined:— PERU. Amazonas: Prov.

Abstract

3. Meriania bicentenaria Rob.Fern., R.Rojas & Michelang., Willdenowia 52(1): 40 (2022). Type:— PERU. Pasco: Prov. Oxapampa, Dist. Oxapampa, Abra Oxapampa-Villa Rica, 2300–2500 m, 10°40’36”S, 75°18’55”W, 06 Aug 2004 (fl., fr.), R. Vásquez, A. Monteagudo, L. Valenzuela, J. Perea & A. Peña 30366 (holotype: HOXA! [accession no. 10648]; isotypes: NY! [barcode 03785787], USM! [accession no. 215491]). (Figures 12–13). Comments:— Meriania bicentenaria is part of the M. macrophylla complex (see comments under M. franciscana for diagnostic characteristics) and differs from other species of Meriania by the combination of densely pubescent abaxial leaf blades, with roughened to dendritic trichomes evenly covering entire surface (Fig. 12B–C), calyces with rounded lobes and without dorsal projections, campanulate, fuchsia to light fuchsia corollas, strongly dimorphic stamens, antepetalous stamens with inflated (bulbous) connectives (Fig. 12E), and antepetalous stamen connectives without dorsal appendages (Fig. 12F). Among Peruvian species, M. bicentenaria most closely resembles M. franciscana but differs by the indument on abaxial leaf blades (densely pubescent vs. sparsely to densely puberulent), petal color (fuchsia to light fuchsia vs. reddish-purple), and the dorsal appendages of the antepetalous stamen connectives (absent vs. blunt ascending). A detailed comparison of M. bicentenaria with other related species can be found in Fernandez-Hilario et al. (2022). Distribution and phenology:— Meriania bicentenaria is a tree endemic to central Peru (Department of Pasco) and grows in montane forests at 2200–2550 m (Fig. 11). It has been collected in flower from June to September, and in fruit from March to November. Specimens examined:— PERU. Pasco: Prov. Oxapampa, Dist.
