Plants pale green or brownish. Stems with branches spreading, loosely foliate, somewhat curved at apices. Stem and branch leaves differentiated. Stem-leaves distinctly longer than broad, 0.8–1.2 mm; apex somewhat obliquely acuminate and subsecund. Branch leaves remote to ± crowded, ovatelanceolate, not or slightly plicate, 0.5–0.8 mm; margins plane to somewhat recurved proximally; apex blunt or acute, usually somewhat oblique and subsecund; costa ending near apex; distal laminal cells 7–9 µm, papillose abaxially. Seta orangebrown to red, 0.7–1.2 cm. Capsule brown to yellowbrown, subcylindric, curved, 2–3 mm; annulus 2 (or 3) -seriate; operculum short to occasionally long-conic; exostome teeth yellowish to brownish yellow; endostome segments somewhat shorter than exostome teeth. Spores 9–13 µm, very finely papillose or nearly smooth.

Discussion

Leskea polycarpa is distinguished by branches typically curved at the apices, clearly differentiated stem leaves that are distinctly longer than wide and somewhat oblique and subsecund at the apices, and capsules that are subcylindric and curved.

Leskea angustata Taylor

Leskea angustata was cited for the flora area by L. E. Anderson et al. (1990). However, no voucher specimens or other literature citations of L. angustata for the area have been seen; it is consequently excluded from this treatment.
