(Melastomataceae) is an Asian genus that extends from central and southern mainland China to Taiwan and the Ryukyu islands. Molecular phylogenetic analyses reveal that the type of is nested in a clade of 20 species, while , a genus previously synonymized in , falls in another distantly related clade of 10 species. Our morphological survey shows that the two clades can be distinguished by several diagnostic features including leaf indumentum, texture, leaf surface sculpture under SEM, presence/absence of yellowish uniseriate trichomes, and capsule morphology. Based on molecular and morphological evidence, is recircumscribed and is resurrected. Description and a list of species are provided for the two genera with the description of a new species, .
(野牡丹科)是一个亚洲属,分布范围从中国大陆中部和南部延伸至台湾以及琉球群岛。分子系统发育分析表明,[属名1]的模式种嵌套在一个包含20个物种的分支中,而[属名2],一个先前在[属名1]中被归为同义词的属,落在另一个与之亲缘关系较远的包含10个物种的分支中。我们的形态学调查显示,这两个分支可以通过几个诊断特征来区分,包括叶毛被、质地、扫描电镜下的叶表面纹饰、是否存在淡黄色单列毛以及蒴果形态。基于分子和形态学证据,[属名1]被重新界定,[属名2]被重新启用。文中提供了这两个属的描述和物种列表,并描述了一个新物种,[新物种名]。
