Phylogenetic Relationships, Character Evolution, and Two New Species in <i>Hemiboea</i> (Didymocarpoideae, Trichosporeae).

ABSTRACT: Two new species, Hemiboea xishuiensis X.X. Bai and Hemiboea cehengensis X.X. Bai, from Guizhou, China, are described here. We performed a molecular phylogenetic analysis of the two new species and 28 taxa within Hemiboea based on ITS and trnL-F, which shows that the phylogenetic tree of Hemiboea forms three major clades: H. fangii Chun ex Z.Yu Li occupies one clade exclusively (Clade I), H. xishuiensis, H. cehengensis, H. parvibracteata W.T. Wang & Z.Yu Li, H. ovalifolia (W.T. Wang) A. Weber & Mich. Möller, and H. kaiyangensis T. Peng & S.Z. He constitute a highly supported clade (Clade II), and the remaining taxa are clustered into the third clade (Clade III). Furthermore, this study traced the evolution of eight
