Abstract:A survey dealing with epiphyllous liverworts in Heishiding Natural Reserve, Guangdong Province, is first reported for epiphyllous liverworts in the west part of the province. Two families, 7 genera, 13 species and 1 variety of epiphyllous liverworts were found. The most common species of them are Leptolejeunea elliptica and Radula acuminata, and then Leptolejeunea hainanensis and Cololejeunea floccosa, which distribute in the evergreen broadleaved forests in ravines at 350m to 600m above sea level. From the viewpoint of bryoflora analysis, epiphyllous liverworts in Heishiding are similiar to that as in Wu yi Mt. (Fujian Province) , in Xishuangbanna and Taiwan. The similiar to each other species in these regions make up 50-70%, which are the major elements of South Asia and have significantly endemic to China species, amounting to 28. 5%.
