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 of Bredia is nested in a clade of 20 species, while Tashiroea, a genus previously synonymized in Bredia, falls in another distantly related clade of 10 species. Based on molecular and morphological evidence, Bredia is recircumscribed and Tashiroea is resurrected. Description and a list of species are provided for the two genera with the description of a new species, T.
Later, Ito and Matsumura established another genus, Tashiroea Matsumura, to accommodate two new species, T. Diels , recognized both genera. He added one Chinese species to Tashiroea and expanded Bredia by describing new species and transferring species from Blastus Lour. He therefore synonymized Tashiroea, accommodating its three species within BrediasectionTashiroea Li With additional descriptions of new species and transfers of other species Hooker ; Cogniaux ; Diels , ; Ohwi ; Li , ; Lauener ; Chen a ; Yeh et al.

Bredia is morphologically closely related to Phyllagathis Blume Blume ; Ito and Matsumura ; Li ; Chen a ; Hansen ; Chen and Renner , another Asian genus with overlapping geographical range.
Delimitation of the two genera was traditionally based on staminal morphology equal or only slightly unequal, isomorphic vs. The vague generic boundary is reflected in the taxonomic history of some species that have been moved back and forth between the two genera by different authors Diels ; Merrill and Chun ; Li ; Chen , b ; Hansen ; Chen and Renner and also in two phylogenetic studies based on very limited taxon sampling Zeng et al.
