Plant Taxonomy and Phylogenetics

Didymodon liae J. Kou, X.‐M. Shao & C. Feng sp. nov., is described and illustrated from Dagzê County in south central Tibet, China. The new species is most similar to Didymodon australasiae (Hook. & Grev.) R. H. Zander, but differs in plants growing loosely in a thin turf, stems without hyalodermis and sclerodermis, margins recurved from just above the base nearly to the apex, laminal cells strongly bulging, mammillose, covered with simple or forked papillae, and costa with a layer of ventral substereids. The new species is contrasted with other similar species of the genus. Information on its distribution and ecology is also provided.
