Abstract
A new species of Orchidaceae, Calanthe yingjiangensis, is described from Yingjiang (Yunnan, China) based on morphology and molecular phylogenetics. This new species is like C. puberula, but it differs from the latter in its midlob of lip with an elliptic yellow spot near the base of the column and four purple veins, triangular lateral lip lobs that is much smaller than middle lobe and twisted lateral sepals. Molecular phylogenetic analyses based on three plastid DNA makers (rbcL, matK and trnL-trnF) and nuclear ribosomal ITS support C. yingjiangensis as sister to C. puberula in Calanthe section Vernae.
