Lejeunea holostipa Spruce (1884: 171) View in CoL .

Type:—BRAZIL. Pará, Spruce L219 (MANCH!, lectotype designated by Grolle & Reiner-Drehwald 1999).—Fig. 10A–G.

Plants light brown, 0.3–5 mm wide. Stems in cross section 80–100 µm in diameter, 7 epidermal cells and 4–6 medullary cells. Ventral merophytes 2 cells wide. Leaves subimbricate to imbricate, ovate, flat to slightly concave, 230–300 × 200–250 µm; margin entire, apex rounded, dorsal and ventral curved; cells orbicular to ovate, conspicuous trigones (but not very large); basal cells 12–22 × 16–18 µm, median cells 16–18 × 13–16 µm, marginal cells 10–13 × 6–8 µm, smooth. Lobules large, 1/2 of leaf length, ovate, more or less inflated, tooth acute, formed by one long cell, 27 × 6 µm, free margin involute, keel curved, and terminal tooth acute. Underleaves distant, orbicular, 90–100 × 100–110 µm, 1.5–2 × stem width, entire, insertion base cuneate. Dioicous. Androecia in principal stem, with 2–5 pairs of bracts. Gynoecia on short shoots with innovations pycnolejeuneoid, bracts obovate, 400 × 300 µm, apex rounded; lobule 180 × 80 µm, bracteole ovate 330 × 270 µm, bifid to 1/3, generally recurved. Perianth with 5 weak to strong keels in the upper half of the perianth, beak long. Vegetative reproduction unknown.

Distribution and habitat:—Neotropical, occurring on Caribbean islands, Mexico, Honduras, Costa Rica, Panamá, Colombia, Venezuela, Guianas, Ecuador, Peru, and Brazil ( Bastos 2017, Schäfer-Verwimp 1999). This species grows on tree trunks in the study area, in lowland rainforest, lower and upper montane rainforests, between 700–3000 m, in the Guatuso-Talamanca, Puntarenas-Chiriquí, Guajira, Magdalena, and Cauca provinces of the Pacific dominion. The record of C. holostipa occurring in the Páramo ( Fig. 11 View FIGURE 11 ), actually belongs to the Cauca province.

Notes:—This species can be recognized as small plants (<600 µm wide), with ventral merophytes 2 cells wide and underleaves distant and fully entire. The section Cyrtolejeunea is composed of two species in the Neotropics, C. holostipa and C. insecta ; the latter species differs by a slightly bifid underleaf and the presence of bracteoles throughout the male spike ( Bastos & Gradstein 2020) and does not occur in the study area.
