Stem leaves spreading, sometimes slightly falcate, 1.2–1.5 mm × 0.5–0.6 mm, broadly ovate-lanceolate, rarely abruptly acuminate, sometimes twisted at apex, cordate at base, moderately decurrent, rarely plicate; margins slightly recurved above, rarely rugose, serrulate throughout; costae double, ca. 1/4 the leaf length; median leaf cells ca. 50 µm × 4–5 µm, sometimes slightly prorate, thick-walled, somewhat porose; alar cells slightly differentiated, quadrate or shortly rectangular, thick-walled, porose, decurrent alar cells distinctly differentiated, rectangular; branch leaves slightly falcate-secund, 0.8–1.1 mm × 0.3–0.4 mm, narrowly ovate-lanceolate. Dioicous. Inner perichaetial leaves erect, ovate- or triangular-lanceolate, rarely plicate, slenderly acuminate, curled at apex, serrulate above, costae double, ca. 1/5 the leaf length, separate at base, median cells thick-walled, porose. Setae ca. 2.5 cm long, reddish brown, usually smooth; capsules horizontal, ovoid to shortly cylindrical, 1.2–2.0 mm × 0.6–1.0 mm, slightly curved; opercula shortly rostrate.
