Stems to 30 cm long, sparsely or densely irregularly pinnately branched. Stem and branch leaves similar, loose or dense, arranged in 3 ranks, narrowly ovate to oblong-ovate, ca. 7 mm long, strongly keeled, often rounded-obtuse or sometimes broadly acute at the apex, narrowed and slightly decurrent at the base; margins entire, plane or reflexed on one side; upper leaf cells elongate-rhombic to rhomboidal; median cells linear-rhomboidal to linear, 90–110 µm × 8–10 µm, thin-walled; basal cells narrowly rhomboidal or sublinear; alar cells lax, rectangular. Perichaetial leaves broadly rounded at the apex. Setae very short; capsules immersed, ovoid, ca. 2 mm long; peristome double; exostome teeth papillose, joined or separated at the apex, keeled, perforate; endostome segments joined by lateral appendages or rarely free.
