After 15 years of field studies in Madagascar, especially focused on the overlooked fern genus (Dryopteridaceae), a synoptic revision of the genus is here presented. Based on more than 2,600 herbarium specimens including collections over 200 years, is the second most diversified fern genus in Madagascar, with 52 species and three subspecies (with 76% of endemism). It is to be compared to the 34 species treated by Tardieu-Blot in 1960 for the "Flore de Madagascar et des Comores" or the 38 species listed by Roux in 2009 in the seminal "Synopsis of the Lycopodiophyta and Pteridophyta of Africa, Madagascar and neighboring islands". The 55 taxa represent five out of seven existing generic sections (sect. and sect. being monotypic and Neotropical): sect. (29 spp. and three subspp.), sect. (17 spp.), sect. (3 spp.), sect. (2 spp.), and sect. (1 sp.). Distribution is given for each species and subspecies, and detailed for each island or archipelago in the Western Indian Ocean (La Réunion, Mauritius, Seychelles, and Comoros). Twenty species and three subspecies are newly described, all but one endemic to Madagascar: Rouhan, Rouhan, Rouhan, Rouhan, Rouhan, Tardieu subsp. Rouhan, Rouhan, Rouhan, Rouhan, Rouhan, (Baker) Krajina ex Tardieu subsp. Rouhan, (Baker) Krajina ex Tardieu subsp. Rouhan, Rouhan, Rouhan, Rouhan, Rouhan, Rouhan, Rouhan, Rouhan, Rouhan, Rouhan, Rouhan, and Rouhan. Morphological description, distribution map, and original illustrations are provided for each new taxon. Novel identification keys to the sections and all species from Madagascar are also presented.
经过在马达加斯加15年的野外研究,尤其聚焦于被忽视的蕨类植物属(鳞毛蕨科),本文对该属进行了综合修订。基于2600余份植物标本馆标本,包括200多年来的采集样本,该属是马达加斯加第二大多样化的蕨类植物属,有52个物种和3个亚种(特有种占76%)。可将其与1960年塔迪厄 - 布洛特为《马达加斯加和科摩罗植物志》所处理的34个物种,或2009年鲁在开创性著作《非洲、马达加斯加及邻近岛屿的石松植物和蕨类植物概要》中列出的38个物种进行比较。这55个分类单元代表了七个现有属组中的五个(组 和组 为单型且分布于新热带地区):组 (29种及3个亚种)、组 (17种)、组 (3种)、组 (2种)和组 (1种)。给出了每个物种和亚种的分布情况,并详细说明了西印度洋各岛屿或群岛(留尼汪岛、毛里求斯、塞舌尔和科摩罗)的分布。新描述了20个物种和3个亚种,除一个外均为马达加斯加特有:鲁汉氏 、鲁汉氏 、鲁汉氏 、鲁汉氏 、鲁汉氏 、塔迪厄亚种鲁汉氏 、鲁汉氏 、鲁汉氏 、鲁汉氏 、鲁汉氏 、(贝克)克拉伊纳 ex 塔迪厄亚种鲁汉氏 、(贝克)克拉伊纳 ex 塔迪厄亚种鲁汉氏 、鲁汉氏 、鲁汉氏 、鲁汉氏 、鲁汉氏 、鲁汉氏 、鲁汉氏 、鲁汉氏 、鲁汉氏 、鲁汉氏 、鲁汉氏 和鲁汉氏 。为每个新分类单元提供了形态描述、分布图和原始插图。还给出了马达加斯加各属组及所有物种的新鉴定检索表。
