general taxon notes:
Species of the Meteoriaceae are mostly distributed in tropical and subtropical regions of the world between the 30° N and the 30° S. They grow on tree trunks, branches, rotten logs, or on shaded, wet rocks. Several studies of the family are useful to the understanding of the Chinese taxa (Buck 1994; Manuel 1977 [1978]; Noguchi 1976; S.-H. Wu & S.-H. Lin 1985, 1986, 1987). Currently, there are 20 genera in the world (Crosby et al. 2000). Eighteen genera are known in China. The genus Pseudotrachypus P. de la Varde & Thér. was recognized by Buck (1994) to include several species of Barbella, such as B. convolvens (Mitt.) Broth., B. spiculata (Mitt.) Broth., and B. stevensii (Renauld & Cardot) M. Fleisch. Here these species are still placed in Barbella. Therefore, Pseudotrachypus is not dealt with in this flora.

METEORIACEAE
蔓藓科  man xian ke
by Wu Peng-cheng and Pei Lin-ying
 
 
Plants often elongate, slender to thick or rather robust, yellowish green, brownish green, or sometimes blackish, glossy or not glossy, in loose or dense mats. Primary stems creeping, usually defoliate, with sparse rhizoids; secondary stems usually pendulous or prostrate, irregularly branched or irregularly pinnately branched, with short or long branches; pseudoparaphyllia absent. Stem and branch leaves similar or dimorphic, broadly ovate, ovate, oblong-ovate, elliptic, or ovate-lanceolate to lanceolate, strongly concave or complanate, deeply plicate or undulate, usually slenderly acuminate to piliferous or suddenly constricted into a short acumen or long ciliate apex, auriculate or not auriculate at the base; margins finely serrulate to coarsely serrate; costae usually single, slender, ending in the upper part of leaf, rarely double, forked, or absent; leaf cells oval, rhombic, rhomboidal, or linear, thin-walled to strongly thick-walled, porose, smooth or papillose; alar leaf cells not particularly differentiated to slightly so, sometimes distinctly differentiated. Dioicous (mostly) or autoicous. Perichaetia lateral; inner perichaetial leaves usually ovate-lanceolate. Setae short to elongate, slender, smooth or scabrose; capsules oblong-ovoid or cylindrical, smooth; opercula conic, shortly rostrate; annuli sometimes differentiated; peristome double; prostome absent; exostome teeth 16, lanceolate, finely papillose or nearly smooth above, sometimes striolate at the base, median line zigzagged; endostome segments linear or linear-lanceolate, smooth or papillose, sometimes keeled and perforate; basal membrane low to high; cilia absent or rudimentary. Calyptrae small, cucullate or mitrate, usually hairy, rarely smooth. Spores spherical or ovoid, roughened or finely papillose.
