摘要
本文是中国蹄盖蕨属植物研究的系列论文的第三篇,对国产轴果蹄盖蕨系植物进行了分类学订正,详细记载了中国产该系植物11种,首次将20余个名称归入该系的一些种下做为异名处理。轴果蹄盖蕨系植物是蹄盖蕨属中自然的一群,以其铁角蕨类型的孢子囊群和囊群益与其它属下类群相区别。本系植物分布于亚洲热带和亚热带山地,常见于山地常绿阔叶林下,海拔500～1800m。在华中和华东地区其分布区北界不超过长江一线。中国西南地区和台湾及日本为该系的三个分化中心。
This paper, third in the series of an account of the genus Athyrium in China, presents a revision of the series Epiraches Ching et Y. T. Hsieh ex Y. T. Hsieh. A total of 11 species are recognized from China, and more than 20 names are reduced to synonyms in the present paper. Ser. Epiraches is a natural group in Athyrium, it is distinguished from all the other groups of the genus by its Asplenioid sori and indusia. The series is entirely Asian tropical, subtropical and primarily montane. Its northern limits in central and eastern China are not beyond the Yangtze River. Southwestern part and Taiwan of China and Japan Islands are centers of diversity for the series, each with more than five species. Some species are disjunctly distributed in southwest China-Taiwan-Japan; one species (Athyrium roseum) occurs discontinuously between Yunnan and Taiwan; one endemic to Hainan (A. hainanense) is the only representative of Athyrium on the island. All members of this series grow in evergreen broad-leaf forests, generally from 500 to 1800 m above sea level. A key to the species, and illustrations of the middle pinnae from different specimens are provided.
