截裂毛蕨

截裂毛蕨（学名：Cyclosorus truncatus (Poir.) Farw.）是金星蕨科毛蕨属植物。植株高可达2米，叶多数，簇生。截裂毛蕨，常出现在生溪边林下或山谷湿地，海拔130-650米。国内分布有台湾、福建、广东、海南、广西和云南。国外分布有日本、缅甸、印度、中南半岛、斯里兰卡、马来西亚、波利尼西亚、菲律宾及澳大利亚北部。

植株高可达2米。根状茎短而直立，粗壮，木质，先端疏被淡棕色的披针形鳞片。叶多数，簇生；叶柄长30-50厘米，基部粗6-8毫米，禾秆色，疏被贴生的棕色、卵状披针形的薄鳞片；叶片长1-1.1米，中部宽30-35（40)厘米，长圆披针形，渐尖头，基部突然变狭，二回羽裂，羽片35对以上，下部5-6对（或更多对）突然变狭，对生，斜向下，相距4-5厘米，基部一对呈卵状三角形，长宽不到1厘米，中部羽片长18-23厘米，中部宽1.8-2.5厘米，披针形，长渐尖头，基部往往稍变狭（我国的大多数标本往往变宽），圆截形，羽裂达1/3-1/2；裂片35-40对，斜展，接近，长3-6毫米，宽3-4毫米，长方形，截头或圆截头，两侧全缘。叶脉两面明显，侧脉斜上，每裂片6-10对，基部一对出自主脉基部，顶端交结成较高的三角形网眼，并自交结点向缺刻延伸出一条外行小脉和第二对的上侧一脉连接，形成斜长方形网眼，第二对的下侧一脉和第三对的上侧一脉均伸到缺刻底部，其余侧脉伸达缺刻以上的叶边。叶草质至纸质，干后草绿色，除羽轴上面有一二针毛外，两面无毛，脉间有泡状突起。孢子囊群生于侧脉中部稍下处，每裂片6-8对；囊群盖中等大，厚膜质，棕色，无毛，宿存。

截裂毛蕨本种变异颇大，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。
