Abstract: One species of the genus Meconopsis (Papaveraceae)ꎬ M. brachynemaꎬ is described as new from southern ar ̄
ea of Qinghai Provinceꎬ China. It probably belongs to subgen. Cunmminsiaꎬ sect. Impeditaeꎬ ser. Impeditaeꎬ and from
the other species of ser. Impeditae differs in its lanceolate ̄linear petalsꎬ fewer and shorter stamens (with filaments only 1
-5 mm long)ꎬ non ̄styled pistilꎬ and ovary with stiffꎬ barbellate hairs.
