To understand the intergeneric relationships in GentianaceaeSwertiinae and some infrageneric phylogeney, a total of 68 species and 1 variant of 14 genera were performed with maximum parsimony and Bayesian inference methods based on the sequences of the nrDNA ITS and chloroplast DNA matK regions. The results revealed that Swertiinae is monophyletic and Bartonia is determined as the most basal genus; Comastoma, Lomatogonium and Gentianella are not monophyletic and are located in one more derived clade; in Swertia, S. sect. Rugosa and S. sect. Swertia, also S. sect. Platynema and S. sect. KingdonWardia are most closely related; Jaeschkea is most closely related to Smacrosperma. Further more, the incongruence between the phylogeny were discussed based on the morphological and molecular data.
