摘要This paper presents the first molecular phylogeny of the genus Hemsleya using nuclear ITS and plastid trnH-psbA, rpl16, and trnL DNA sequences to examine the relationships among Hemsleya species. Phylogenetic relationships were elucidated using a combined analysis of all four datasets, however, the number of parsimony-informative characters was still insufficient to resolve all relationships. Parsimony and Bayesian trees were highly congruent. Twenty-three species of Hemsleya split into two major clades corresponding to two subgenera, i.e., subg. Graciliflorae and subg. Hemsleya. These results are partly in agreement with Li's sectional classification. However, the molecular data are inconsistent with Li's classification at the subsectional level. The molecular phylogeny revealed a striking overall correlation between the phylogenetic relationships of the species and their geographical distribution. The Kangdian ancient landmass could be the center of origin of the genus.
