摘要

摘要蕨类植物Didymochlaena的特征是有鳞状的根状茎和叶柄，簇状和二回羽状叶，二分生的羽片，每个羽片少于11个sori。很长一段时间以来，该属只有一个物种被广泛认可。最近，根据形态学和/或分子证据，分别确认了马达加斯加和亚太地区的6个和7个物种。在这项专题研究中，我们在全球范围内识别了22个物种，其中6个被描述为新物种：高山D.alpina、亚马逊D.amazonica、喀麦隆D.Cameronesis、共聚D.comorensis、立方D.cubensis和中美洲D.mesomericana。提供了所有物种的钥匙，并提供了关于其分布和栖息地的详细描述、插图和信息。

Systematics of the Fern Genus Didymochlaena (Didymochlaenaceae)

Abstract The fern genus Didymochlaena is characterized by having scaly rhizomes and petioles, tufted and bipinnate leaves, dimidiate pinnules, and fewer than 11 sori per pinnule. For a long time only one species was widely recognized in the genus. Most recently, six and seven species from Madagascar and Asia-Pacific regions, respectively, have been recognized based on morphological and/or molecular evidence. In this monographic study we recognize 22 species worldwide, six of which are described as new: D. alpina, D. amazonica, D. cameroonensis, D. comorensis, D. cubensis, and D. mesoamericana. A key to all species is provided, and detailed descriptions, illustrations, and information on their distribution and habitats are given.
