Molecular phylogeny of (Malpighiaceae) reveals a new species from Southwest China.

is an Asia-endemic genus of Malpighiaceae currently placed in the tetrapteroid clade, representing one of the seven inter-continent dispersions from New to Old World. A molecular phylogeny based on sequences of the internal transcribed spacer (ITS) region was recovered for the first time for the genus. Our results showed that the most recent common ancestor of probably originated in the South Indo-China Peninsula and diversified in this region.
