Lembophyllum clandestinum

Loose open wefts on tree bases, rocks, logs and soil. Secondary stems ±erect to scrambling, divided into a basal stipe section and a sparingly bipinnately branched frond section; branches blunt to loosely cuspidate, often attenuate; central strand indistinct. Leaves imbricate, terete-foliate, widely-spreading when moist, erecto-patent to appressed when dry, orbicular, wider than long, strongly concave, inflated-smooth when moist, loosely wrinkled or slightly baggy when dry; apex obtuse; costa weak, usually double and failing below midleaf, sometimes absent; margins serrulate throughout or only at apex, incurved; midlaminal cells linear to short-linear, 12.5–20 (–25) μm long, 3.5–5μm wide, weakly prorate; laminal cells towards central base 35–43 μm long long, 5–6 μm wide; apical cells irregularly short-rhombic, (7.5–) 10–15 (–18) μm long, c. (2.5–) 5 μm wide; marginal cells at midleaf 15–20 μm long, c. 3.75 μm wide. Stem leaves longer than branch leaves, with a larger alar group, (0.7–) 1–1.3 mm long, 1.2–1.8 mm wide; alar cells quadrate or irregular, c. 9–22 μm long, c. 7–14 μm wide, forming a dark group 8–12 cells wide and extending 6–8 cells toward apices. Branch leaves 0.75–0.9 mm long, 1–1.25 mm wide. Seta c. 3 cm long, red-brown, smooth. Capsules horizontal, ovoid to obloid, sometimes narrowly so, symmetric or curved, 1.2–1.5 mm long. Operculum blunt to apiculate, c. 0.75 mm long.
