生长环境
主要生长于海拔130-650米溪边林下或山谷湿地。
分布范围
主要分布于台湾（台北、南投、台南、高雄、屏东、台东）、福建（南靖）、广东（英德）海南（陵水、尖山）、广西（大瑶山、百色、武鸣、大明山）、云南（金平、河口、西双版纳）。也广布于日本、缅甸、印度、中南半岛、斯里兰卡、马来西亚、波利尼西亚、菲律滨及澳大利亚北部。
本种提示
本种变异颇大，我国产的许多标本，其羽片基部往往变宽，但其他特征与模式标本无异。尖裂毛蕨Cyclosorus truncatus var. acutiloba Ching in Bull. Fan Mem. Inst. Biol.Bot. ser. 8：219. 1938.产云南耿洪和木安（Keng Hung & Muang Hing）。秦后来又将之升为C. kenghungensis Ching in Herb.。正如原描述所说，除了叶草质，裂片先端尖或微尖外，和原变种无异。北京标本馆仅存一中部羽片，其侧脉在缺刻下有2 1/2-3对，脉间无泡状凸起。
