| Abstract: |
| Three new species of the genus Meconopsis(Papaveraceae)from China are described in this paper.(1)Two species are described as new from northwest Sichuan Province, China. Of them M. pleurogyna is probably related to M. lhasaensis Grey-wilson, differing in its narrower, entire leaf blades and longitudinally 4-ribbed ovary; M. angustipetala is probably related to M. henrici Bur. & Franch., differing in its smaller, glabrous leaf blades, and peculiar linear-oblanceolate petals.(2)One species M. brachynema, is described as new from southern Qinghai Province, China. It probably belongs to subgen. Cunmminsia, sect. Impeditae, ser. Impeditae, and from the other species of ser. Impeditae differs in its lanceolate-linear petals, fewer and shorter stamens(with filaments only 1-5 mm long), non-styled pistil, and ovary with stiff, barbellate hairs. |
