Abstract

(Fabaceae), a new species from Danxiashan National Nature Reserve in Guangdong Province, is described and illustrated. The new species is morphologically similar to , but it can be easily distinguished by its thin leathery leaflets and long peduncles. Phylogenetic analysis based on ITS confirmed that the new species belongs to Lespedezasubg.Macrolespedeza. The new species is the first known species of endemic to Danxia landform and is currently only known from Mount Danxia, Guangdong.

摘要

豆科（Fabaceae）一新种，采自广东省丹霞山国家级自然保护区，予以描述并附图。该新种在形态上与[某物种]相似，但因其薄革质小叶和长花梗而易于区分。基于ITS的系统发育分析证实，该新种属于胡枝子属（Lespedeza）大胡枝子亚属（subg. Macrolespedeza）。该新种是丹霞地貌特有的首个已知物种，目前仅知分布于广东丹霞山。
