Stem leaves triangular, occasionally ovate-triangular, 1.5–2.8 mm long, 0.8–1.2 mm wide, concave, not or occasionally slightly plicate; costae extending 1/2–2/3 leaf length, occasionally with an indistinct spine; apex acuminate, without a hair-point; margins entire, rarely denticulate near apex, sometimes recurved at base and apex. Branch leaves ovate or triangular, 1.5–2.1 mm long, 0.8–1.1 mm wide; apex acute or obtuse and apiculate; margins denticulate near apex. Setae 20–25 (–40) mm long, red-brown, smooth.
