Abstract
Gentiana daofuensis, a new species of the family Gentianaceae, is described and illustrated here. Currently, this species is known only from Daofu County, Sichuan Province, China. Phylogenetic analyses based on chloroplast genome data indicate that it belongs to G. section Chondrophyllae s.l. Morphologically and genetically, it is closely related to G. crassuloides but can be clearly distinguished from the latter by its shorter calyx and pale blue-purple corolla with numerous dark blue short stripes or spots.
Key words: Chloroplast genome, Gentiana, Qinghai-Tibet Plateau, section Chondrophyllae

Diagnosis. Gentiana daofuensis is distinguishable from all other similar species of the genus by the combination of the reniform leaves on the upper stem and the pale blue-purple corolla with numerous dark blue short stripes or spots.
Etymology. The specific epithet “daofuensis” is derived from the type locality of the new species, Daofu County, and the Latin suffix -ensis, indicating the place of origin or growth.
Vernacular name. Chinese mandarin: dao fu xiao long dan (道孚小龙胆).
