Abstract
In the present study, a new species Codonopsis gongshanica is described. This species is endemic to Gaoligong Mountains of NW Yunnan. Codonopsis gongshanica is similar to Codonopsis bhutanica and Codonopsis subsimplex in morphology, but it can be separated from these species by its simple stem, sub-rosulate leaves, short petiole, solitary flower, and diagnostically dark purple ring just below the corolla throat. Our molecular phylogenetic analysis based on chloroplast DNA fragments (atpB, matK, rbcL, petD with petB-petD, and psbA-trnH) shows that the new species is well recognized in our molecular tree, with its taxonomic position revealed.
