Adiantum viscosum A. Cádiz-Véliz & A.E. Villarroel, sp. nov. (Fig. 2, 3) Diagnosis: — Adiantum viscosum differs from A. gertrudis and A. glanduliferum by the presence of capitate and glandular trichomes covering the entire aerial part of the plant, including pinnules, rachis, petioles and petiolules, which produce a sticky and aromatic resin. Type:— CHILE. Valparaíso Region: San Felipe de Aconcagua Province, Putaendo, Cordón del Tabaco, Quebrada de Granallas, 32°36’39.41” S; 70°46’44.72” W, 1330 m elevation, 10 October 2021, A . Cádiz-Véliz & B. Palma-Villalobos 801 (holotype: JBN!; isotypes: SGO!, CONC!). Description:— Terrestrial and saxicolous herb. Rhizomes short and creeping, 2–4 mm in diam. Rhizome scales lanceolate, emarginate, 1.5–2.0 mm long, brown with entire margins, not ciliate. Fronds 12–27 cm long. Petioles 1–1.5 mm diam., 4–13 cm long, covered with lanceolate scales 1.5–2.5 mm, brown, grouped at the base. Blades 2–pinnate, rarely 3–pinnate, 9–15 × 6–9 cm, deltoid in outline, approximately half the length of the frond. Rachises straight. Petiolules 1–5 mm long. Pinnules 8–15 × 8–25 mm, flabellate to reniform in outline, base cuneate-symmetrical or asymmetrical, alternate, terminal pinnae usually larger than underlying ones, margin of sterile pinnules crenulateserrate, margin of fertile pinnules folded towards the underside, forming a false indusium. Veins dichotomous, terminating between the crenulate margins. Trichomes on the aerial parts of the plants, (including pinnules, rachis, petioles and petiolules) dense, capitate, glandular, 0.4–0.6 mm, 3–4 cellular, yellowish, hyaline, exuding a sticky and aromatic resin. False indusia 5–15 per pinnule, rectangular or reniform, with a depressed and hyaline basal margin. Spores not observed. Etymology:— The specific epithet refers to the viscous resin produced by the glandular trichomes. Distribution and habitat:— Currently, the only known locality of the species is the one reported in this manuscript, and corresponds to a southwest-exposed slope in the Quebrada de Granallas (Fig. 1), where it occupies an area Quillaja saponaria Molina (1782: 354) and Lithraea caustica Hooker & Arnott (1833: 175) (Luebert & Pliscoff 2017). Adiantum viscosum grows accompanied by Tropaeolum azureum Colla in Bertero (1832: 147), Colliguaja odorifera Molina (1782: 354), Porlieria chilensis, and Kageneckia oblonga Ruiz & Pavón (1798b: 289). Phenology:— Adiantum viscosum initiates the formation of its fronds in mid-winter, after the first rains (June– July). The aerial part dies during the dry and warm summer (December–March). Conservation status:— Using IUCN criteria (2012), Adiantum viscosum is proposed as Critically Endangered (CR) B1+B2ab (i,ii,iii), because the extent of occurrence (EOO) is et al. 2012). In addition, the Cordón del Tabaco is threatened by mining projects, overgrazing, burning, drought, and unregulated tourism, which could affect the species (Madrid et al. 2018, Cádiz-Véliz & Aliaga-Reyes 2019). Adiantum viscosum is not present in any area of the Sistema Nacional de Áreas Silvestres Protegidas del Estado (SNASPE). Additional specimens examined: Adiantum gertrudis — CHILE.

According to Escobar (2012), there are two kinds of floral appendages around the staminal tube or urn in Miersia: 1) the upper pair of appendages are of staminal origin and 2) the four lateral appendages, one pair on each side of the staminal tube, are of tepaliferous origin. Consequently, mentions to "tepaliferous appendages" in diagnoses, descriptions, identification key and figure captions of our recent article (García et al. 2022) should be changed to "floral appendages", to denote the mixed nature of those structures in most species of Miersia.

Ivania juncalensis Al-Shehbaz (2010: 345). (Fig. 1, 3) Type: — CHILE. Región de Valparaíso, Provincia de Los Andes, Valle del Río Juncal, 2500 m.a.s.l., 15 December 1976, Otto Zöllner 9165 (Holotype NA 5434). Description (Modified from Al-Shehbaz 2010): —Herbs, perennial, glabrous throughout. Caudex woody, densely covered with petiolar remains of previous years, several branches terminated in rosettes. Stems 8‒30 cm, erect, leafy. Basal leaves rosulate, not fleshy, more or less leathery; petiole 3.5‒9 cm; blade 2‒8 × 0.7‒3.5 (5) cm, oblong to lanceolate, pinnatifid to pinnatisect, base cuneate. Cauline leaves 1‒5 × 0.1‒1 cm, petiolate, linear-oblanceolate, entire to pinnatifid. Raceme elongated in fruit 5–12 cm long, branched, with cauline leaves up to the first flower of each branch; pedicels 1‒2 cm, divaricate-ascending. Sepals 2.5‒3 mm, ovate; petals 6‒7.5 × 2.5‒3 mm, white, spatulate, claw 3‒3.5 mm long; filaments 3‒3.5 mm long; anthers ca. 1 mm long, oblong; gynophore absent (~ 0.5 mm long in fruit); style 0.2‒0.5 mm long; stigma capitate, strongly 2‒lobed. Fruit siliqua, 2.5‒5 × 0.1‒0.2 cm, linear, slightly curved, terete, each valve with 2-3 longitudinal veins, replum terete, septum complete and veinless; seeds 2‒3 × 1 mm, uniseriate on each valve, numerous, pyramidal, acuminate, brown. Distribution and habitat: — Ivania juncalensis is endemic to the Andes of the Región de Valparaíso (Al-Shehbaz 2010, Rodríguez et al. 2018) and, until now, it is only known from the locality reported in this article. It is located in the private protected area Parque Andino Juncal, in the Río Juncal valley, Región de Valparaíso, Chile (Fig. 2). It is found between 2500 and 2900 m.a.s.l. in the “Mediterranean Andean dwarf scrub of Chuquiraga oppositifolia D. Don (1832: 392) and Nardophyllum lanatum (Meyen) Cabrera (1954: 63) ” vegetation type, which is found on high hillsides of the Andes between the provinces of Choapa and Colchagua (Luebert & Pliscoff 2017). However, I. juncalensis grows exclusively in rock crevices (Fig. 3), generally oriented towards the southwest, where it was observed along with Bowlesia tropaeolifolia Gillies & Hook. (1830: 325), Cystopteris apiiformis Gand (1913: 28), and Valeriana stricta Clos ([in Gay] 1848: 235). Based on field observations, we estimate its population size is less than 250 mature individuals. Studied material: — CHILE. Valparaíso: Los Andes Province, Juncal River Valley, Parque Andino Juncal, La Yesera sector, on a rocky slope with SW exposure, 32°54’14”S; 70°05’40”W, 2870 m.a.s.l., November 29th, 2021, A. Cádiz-Véliz & N. Marín 802 (JBN!, EIF!, VALPL!, SGO!, CONC!); February 14th, 2022, A. Cádiz-Véliz & B. PalmaVillalobos 961 (EIF). Ecology: —During the visits we did not observe pollinators, but we presume the species is pollinated by bees and/or flies due to the presence of nectaries and its floral morphology. After fruits dehisce, seeds are primarily gravity dispersed and helped by wind and water. It is likely that most seeds fall near the mother plant, which could partially explain its extremely restricted distribution. Phenology: —Flowers from early November to late December, and fruits from mid-December to mid-February. Conservation status: —The conservation status of I. juncalensis had not been assessed until now, although Warwick et al. (2011) mentioned it should be listed as “highly endangered”. Here we propose to list it as Critically Endangered (CR) B1+B2a (i,ii,iii) following the IUCN (2012) criteria, as its extent of occurrence (EOO) is et al. 2012). Some individuals showed signs of herbivory and we observed exotic lagomorphs in its habitat. Moreover, in the Andes of the Valparaíso Region there is goat and cattle farming, and multiple mining projects, such as the Nutrex mining project located less than 3 km away from the collection locality (Fig. 2). Taxonomic and phylogenetic considerations: The type species of Ivania was originally described by Johnston (1929) in Cardamine L. (1753: 654) and later transferred to Ivania (Schulz 1933). However, morphological differences to distinguish both genera have not been proposed. The genus Cardamine (Cardamineae tribe) is characterized by the presence of siliquae linear to subulate, latiseptate or rarely subterete with valves dehiscing elastically, and flattened replum, while Ivania (Thelypodieae) has siliquae linear and terete, with valves not dehiscing elastically, and terete replum (Appel & Al-Shehbaz 2003). Nevertheless, phylogenetic analyses using ITS clearly placed both Ivania species within the Thelypodieae tribe, along with other South American genera such as Chilocardamum O.E. Schulz (1924: 179), Pringlea W.Anderson ex Hook. f (1845: 238), and Polypsecadium O.E. Schulz (1924: 176), although the phylogenetic resolution within this tribe is very poor (Warwick et al. 2011). Even though the monophyly of Ivania was shown by Warwick et al. (2011), it is difficult to diagnose this genus considering several outstanding morphological differences between both species (Al-Shehbaz, 2010). For example, Ivania cremnophila has an evident gynophore of 2–4 mm long, while it is absent to only 0.5 mm long in I. juncalensis (absent according to Al-Shehbaz (2010)). Before the description of I. juncalensis, the presence of a gynophore longer than 2 mm was used in the generic key of Appel & Al-Shehbaz (2003) to separate Ivania from other similar genera; therefore, a clear morphological distinction of Ivania in relation to other genera in Brassicaceae is lacking. However, Ivania is characterized by entirely glabrous plants, while most species of related genera have simple and/or forked hairs. The presence of longitudinal veins on the fruit valves of Ivania juncalensis is a potential synapomorphy shared with other genera in Thelypodieae, such as Mostacillastrum and Stenodraba O.E.
