New taxa and nomenclatural changes in Bredia (Sonerileae, Melastomataceae)

A recent phylogenomic analysis has unveiled the first highly resolved phylogeny for the genus <i>Bredia</i>, clarifying long-standing uncertainties in species boundaries among taxonomically debated groups. Based on these findings, we propose a taxonomic revision encompassing the following updates: (1) <i>B. latisepala</i>, <i>B. longearistata</i>, and <i>B. longiradiosa</i> are synonymized under <i>B. esquirolii</i>; (2) <i>B. dulanica</i> C.L.Yeh, S.W.Chung & T.C.Hsu is incorporated within <i>B. hirsuta</i>; (3) two new combinations are established, alongside the formal recognition of three new species and one new variety (Suppl. material 1); (4) <i>Bredia bullata</i> S.Jin Zeng & N.H.Xia is regarded as a later homonym and therefore illegitimate name for <i>B. bullata</i> J.H.Dai & Ying Liu. Morphological descriptions, color plates, and updated distribution maps are provided for relevant taxa, supplemented by a key to all recognized <i>Bredia</i> species.
