general taxon notes:
Pterobryopsis is primarily tropical and subtropical in distribution. There are about 30 species in the world (Crosby et al. 2000), with six species known in China. Pterobryopsis angustifolia Nog., P. crassiuscula (Cardot) Broth., P. cucullatifolia S. Okamura, P. gedehensis M. Fleisch., and P. subcrassicaulis Broth. listed by Redfearn et al. (1996) cannot be verified at this time.

Hedwigia 45: 56. 1905.
 
Plants medium-sized to large, sometimes slender, yellowish green, dark green to brown below, often glossy, in compact or loose mats. Primary stems prostrate, elongate, with brownish rhizoids; secondary stems erect-ascending or pendulous, often dendroid, irregularly branched, sometimes with flagelliform branches, rarely branches attenuate at the apex. Leaves imbricate or loosely appressed when dry, usually ovate, strongly concave, shortly acuminate, rarely acute at the apex; margins entire or denticulate near the apex; costae single, extending to mid-leaf, rarely double or absent; leaf cells rhomboidal or linear, smooth; basal cells lax, reddish brown, porose; alar cells often differentiated, thick-walled. Gemmae often present, fusiform. Dioicous. Setae short or elongate; capsules exserted, oblong-ovoid; opercula conic, shortly rostrate; annuli distinctly developed, deciduous; peristome double; exostome teeth lanceolate, trabeculate on the inner surface; endostome segments often reduced or absent, sometimes linear, as long as the teeth; basal membrane very low. Calyptrae mitrate or cucullate. Spores spherical, large, finely papillose.
