Abstract

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 ofBrediais nested in a clade of 20 species, whileTashiroea, a genus previously synonymized inBredia, 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,Brediais recircumscribed andTashiroeais resurrected. Description and a list of species are provided for the two genera with the description of a new species,T.villosa.
