Metagentianajiangyouensis, a new species of Gentianaceae from Sichuan, China, is described and illustrated. This new species is similar to Metagentianavillifera, but differs by the fact that the plant is glabrous and has 1-4 flowering stems, well-developed basal vegetative rosettes, a pale purple corolla with dark purple spots on the tube and erose or denticulate, non-fringed plicae margins. It also somewhat resembles M.rhodantha, but can be easily distinguished by having shorter stems, entire leaf margins, smooth, shorter sepal lobes, spotted corolla tubes, non-fringed plicae and narrowly winged seeds.
