Description
Summary:Verdesmum menglaense (C. Chen & X. J. Cui) H. Ohashi & K. Ohashi is a rare species in the tribe Desmodieae (Fabaceae) from Southwest China. The morphological observation shows that the species has minute capitate stigma and ebracteolate calyces, which are entirely different from the funnel-shaped stigma and bracteolate calyces of the genus Verdesmum H. Ohashi & K. Ohashi, but are consistent with those of the genus Hylodesmum H. Ohashi & R. R. Mill. The generic placement of V. menglaense within Hylodesmum was further supported by molecular evidence. Therefore, this species should be returned to Hylodesmum as H. menglaense (C. Chen & X. J. Cui) H. Ohashi & R. R. Mill. A full description including floral characters, a colour plate and a distribution map are first provided here for this species. After excluding the solo representative in China, Verdesmum should be removed from the record in Flora of China.
