Abstract

The monotypic genus Penzigiella Fleisch. is reviewed. Penzigiella cordata (Hook.) Fleisch. occurs in India, Nepal, Sikkim, Bhutan, Burma and Thailand. A lectotype (Nepal, Wallich s.n. TCD) is designated. Descriptions, illustrations and a distribution map are provided in addition to remarks on bryogeography, morphology, nomenclature and taxonomy. Penzigiella, named in honor of Dr. Ottone Penzig, was established by Fleischer in 1905 (1906). At the time only a single species, P. cordata, was recognized. Later Brotherus (1922) added a second species, P. robusta, which Noguchi (1966) transferred to the genus Neodolichomitra Nog. (Hypnaceae). There has been no recent taxonomic study of the genus, especially in terms of its typification and relationships. Moreover, information on distribution of the genus has not been sufficiently summarized. This paper attempts to correct this situation. This work is based on about 120 specimens received on loan from BM, EGR, FH, H, L, MO, NICH, NY, S-PA, TCD, TENN, TNS and us. Spellings of place names, where
