摘　　要：研究了云南产复叶耳蕨属（ＡｒａｃｈｎｉｏｄｅｓＢ１．）植物，提出了新的分类处理。云南共有本属植物２０种２变种，其中包括１新组，３个改级新组合，７个云南分布新记录，并清理出了５４个云南及其他省区种类的新异名。The gensus Arachniodes B1. in Yunnan was exhaustively studied in the present paper. Through wide field observations and vast herbaria studies, the rhisome habits and the characteristics of scales on the base of stipe, such as shape, texture and luster, were found to be relatively stable, which can be used to determine the subdivision of this genus. Some useful characters are the paleae or indument on the frond, the degree of complexity, the shape of the apical part of lamina or that of the hasal pinna, the shape and dissection of the ultimate pinnule, the texture and luster of lamina, the positions of son on the pinnule and the edge of indusium, which can be moderately applied to recognize species. The size of frond, lamina or Pinna, the angle between rachis and rachlet, the distribution of son on lamina and so on are unstable characters, which can not correctly define species. As a result, the revised classification of this genus in Yunnan was provided. There are 20 species and 2 varieties, including a new section, 3 new statuses, 6 species and a variety newly recorded to Yunnan and 54 new synonyms from Yunnan and other provinces.
