摘要

标题Flemingia亚科的分类订正。介绍了基于形态学和分子信息(matK和ITS)的狼尾草属植物。该亚属包括6个草本分类群(F. gracilis、F. mukerjeeana、F. nilgheriensis、F. rollae、F. tuberosa和F. vestita)。所有的种类，除了风叶菌是印度特有的。形态学证据和分子系统发育显示该亚属为单系植物。然而，由于其独特的生态和花序，其系统位置仍不清楚。描述了一新种F. mukerjeeana，并对4种二分种F. gracilis、F. nilgheriensis、F. tuberosa和F. vestita进行了分型。此外，还对所有物种进行了描述、图解和生态学讨论。为方便鉴定，本文还提供了一个包括最近在泰国发现的物种F. sirindhorniae的分类钥匙。

Taxonomic revision and molecular phylogeny of Flemingia subgenus Rhynchosioides (Leguminosae)

A taxonomic revision of Flemingia subg. Rhynchosioides based on morphology and molecular information (matK and ITS) is presented. The subgenus comprises six herbaceous taxa (F. gracilis, F. mukerjeeana, F. nilgheriensis, F. rollae, F. tuberosa and F. vestita). All species except F. vestita are endemic to India. Morphological evidence and molecular phylogeny revealed that the subgenus is monophyletic. Nevertheless, the systematic position of F. tuberosa remains unclear on account of its unique ecology and inflorescence. A new species, F. mukerjeeana, is described and four binomials, namely F. gracilis, F. nilgheriensis, F. tuberosa and F. vestita have been lectotypified. Furthermore, all species have been described, illustrated and their ecology discussed. A taxonomic key including the recently described species from Thailand, F. sirindhorniae, is also provided for easy identification.

期刊介绍： An international electronic-only journal on the biodiversity, evolution and biogeography of plants (systematics, floristics, phylogeny, morphology, anatomy). For floristic studies, the focus is on tropical Africa south of the Sahara; tropical Southeast Asia with a strong emphasis on Malesia; South America with emphasis on the Guianas. The language is English.
