2.1. Cheilolejeunea adnata (Lehmann) Grolle (1977: 529) var. adnata View in CoL View at ENA —
Jungermannia adnata Lehmann (1834: 46) .
Type:— CUBA. In caduce Oreodoxae regiae, Pöppig s.n. (W, lectotype designated by Grolle 1977).— Fig. 2I–M View FIGURE 2 .
Plants yellowish green to light brown, 0.6–0.9 mm wide. Stems in cross section 60–100 µm in diameter, 7–8 epidermal cells, 16–28 × 10–14 µm; 9–10 medullary cells, 9–16 × 5–11 µm. Ventral merophytes 2 cells wide. Leaves subimbricate to imbricate, generally orbicular to ovate, fully flat, 415–500 × 350–500 µm; margin entire; apex broadly rounded; cells orbicular to ovate, cuticle smooth, inconspicuous trigones; basal cells 22–27 × 15–21 µm, median cells 18–29 × 16–20 µm, marginal cells 11–16 × 9–11 µm. Lobules rectangular to ovate, 1/4 leaf length, free margin involute, tooth acute, formed by a cell long, straight to slightly curved, 10 × 25 µm, keel arched. Underleaves distant, orbicular, 1.5–2.5 x wider than the stem, 150–210 × 80–160 µm, bifid to 1/3–1/2, with a V-shaped sinus, margin entire, base cuneate. Dioicous. Androecia on branches, with 5 pairs of bracts. Gynoecia on branches, with a lejeuneoid innovation (sometimes absent), bracteoles obovate, 620 × 390 µm, bifid to 1/8. Perianth 3-keeled, the keels weak, beak short. Vegetative reproduction by means of caducous leaves with hyaline rhizoids on the margin.
Distribution and habitat:—Neotropical, occurring in the Caribbean islands, Costa Rica, Panamá, Colombia, Venezuela, Ecuador ( Gradstein 2020, 2021), Guyana, Suriname, and Brazil ( Bastos 2017). In the study area, generally grows epiphytic on tree trunks and shrubs, below 2000 m, in the lowland rainforest and lower montane rainforest, in the Puntarenas-Chiriquí, Guatuso-Talamanca, Trinidad, Magdalena, Cauca, Chocó-Darién, and Venezuelan provinces of Pacific dominion ( Fig. 3 View FIGURE 3 ).
Notes:—The species is easily distinguished by the presence of deciduous leaves with rhizoids on their margin, lobules ca. 1/4 of the length of the leaf, with a prominent tooth, and distant underleaves, slightly wider than the stem, orbicular, with cuneate bases.
