野牡丹属（野牡丹科）是一个亚洲属，从中国大陆中部和南部延伸到台湾和琉球群岛。分子系统发育分析显示，Bredia的类型嵌套在Glade的20个物种中，而先前与Bredia同属的Tashiroea属属于另一个远亲的10个物种的clack。我们的形态学调查表明，这两个支系可以通过几个诊断特征来区分，包括叶毛被、质地、扫描电镜下叶表面雕刻、黄单毛毛的存在/缺失以及蒴果形态。基于分子和形态学的证据，布雷亚被重新界定，塔希罗亚被复活。本文对这两个属作了描述和种表，并对一个新种——小叶草进行了描述。
Bredia (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 Bredia is nested in a Glade of 20 species, while Tashiroea, a genus previously synonymized in Bredia, falls in another distantly related clack 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, Bredia is recircumscribed and Tashiroea is resurrected. Description and a list of species arc provided for the two genera with the description of a new species, T. villosa.
