general taxon notes:
T.-Y. Chiang and C.-M. Guo (1989) reported D. angustifolia var. gemmiphylla Fleisch. from Taiwan, but from the description and illustration it appears to be close to D. contorta C. Müll. The occurrence of this species in China awaits the confirmation of the specimens.

Leaves spirally crowded, flexuous when dry, erect-patent when wet, narrowly lanceolate to oblong-lanceolate, 1.5–2.0 mm × 0.25–0.50 mm, gradually long acuminate, with a well differentiated border of 2–3(–4) rows of linear cells; margins entire, recurved on both sides; costa single, strong, somewhat carinate, ending some distance below the apex; leaf cells smooth, irregular in shape, oblong, fusiform to narrowly rhomboidal, 22–33 µm × 7–10 µm, moderately thick-walled, becoming shorter near apex, longer and laxer at leaf base. Synoicous. Perichaetial leaves smaller, ovate, 0.2 mm long, ecostate. Setae lateral, 3–5 mm, reddish, smooth below, scabrous above; capsules 1.0–1.3 mm long, ovoid, inclined to erect; exostome teeth and endostome segments nearly the same length, ca. 2/3 the length of the theca, papillose.
