general taxon notes:
The genus consists of some 170 species in the world (Crosby et al. 2000), and 17 species are recognized in China. Numerous recent studies on the genus Philonotis(Koponen & Norris 1996; Koponen 1998, 1999; Virtanen & Koponen. 1998) have provided new insights on the treatment of Chinese species of this genus.

5. Philonotis Brid.   泽藓属   ze xian shu
Bryol. Univ. 2: 15. 1827. Bartramia subgen. Philonotis (Brid.) Hampe, Ann. Sci. Nat., Bot., ser. 5, 3: 370. 1865.
 
Plants small to rather large, dull or glossy, in loose or dense tufts. Stems reddish, erect, often branched below the fertile buds; radiculose below; central strand developed. Leaves mostly erect, appressed when dry, erect-patent or secund when moist, ovate- to narrowly ovate- or triangular-lanceolate, acuminate at apex, rarely obtuse; margins plane or recurved, serrulate or serrate, unistratose; costae strong, usually excurrent, sometimes ending below the apex; apical leaf cells shortly rectangular or rhombic; median cells narrowly rhombic or hexagonal, usually prorate at upper cell ends, sometimes prorate at both ends, rarely smooth; basal cells larger, lax, rectangular, papillose at upper or lower ends or smooth; alar cells weakly differentiated. Dioicous, rarely autoicous. Setae solitary, elongate, straight; capsules nearly spherical, asymmetric, inclined or horizontal; furrowed when dry; neck short; mouth broad; opercula conic at base, shortly rostrate; peristome double; exostome teeth lanceolate, with a median zigzag line, papillose above or throughout, trabeculate; endostome segments split, perforate, papillose; cilia 1–3 or not developed. Calyptrae shortly cucullate. Spores spherical or reniform, papillose.
