摘　　要：广东省黑石顶自然保护区的叶附生苔类植物调查,为该省西部有关叶附生苔类的首次报道,发现了2科、7属、13种和1变种。它们分布于海拔350—600m之间的沟谷常绿阔叶林内,最习见种类为尖叶薄鳞苔(Leptolejeunea elliptica)和尖舌扁萼苔(Radula acuminata),其次系海南薄鳞苔(Leptolejemea hainanensis)和棉毛疣鳞苔(Cololejeunea floccosa)等。从区系角度分析,黑石顶自然保护区与我国西双版纳、福建武夷山和台湾的叶附生苔类分别有50—70％的种类相似,它们以南亚成分为主,并有明显的我国特有成分(28.5％)。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%.
