Impatiens liupanshuiensis (Balsamianceae), belonging to I. subgen. Impatiens, is recognised as a new species from Guizhou, China and it is described and illustrated. It is morphologically similar to I. xanthocephala W.W. Sm. in its yellow flowers, extremely small basal lobes on lateral united petals, broadly-dolabriform distal lobes and funnelform lower sepal. However, it is distinctive in the number of lateral sepals, teeth on the margin of lateral sepals, the recurvature of the dorsal petal, the number of lateral veins, the shape and size of the lamina and the type of lamina margin. A detailed description of the new species and colour photographs are provided. Its geographical distribution and morphology are also compared to similar species.

The genus Rhododendron is widely distributed, lives in diverse habitats, and its group structure is complex. An in-depth analysis of its geographical distribution pattern and characteristics can provide a basis for conservation and utilization

Impatiens bijieensis X.X. Bai & L.Y. Ren, sp. nov. from northwest Guizhou Province, China, is described and illustrated. This new species is distributed discontinuously in Jiulongshan, Dafang County and Dajiucaiping, Hezhang County, both of which are in the Wumeng Mountain area, a karst plateau landform. The new species is morphologically similar to I. pterosepala Hook.f., I. lasiophyton Hook.f. and I. leptocaulon Hook.f. in height and flower shape and it especially resembles I. lasiophyton in pilosity. However, it differs in its deep purplish-red flower, 2-lobed lower sepal apex and cylindrical capsule. A detailed description, colour photographs and a provisional IUCN Red List assessment are provided along with discussions of its geographical distribution, ecology and morphological relationships with other similar species.

Impatiens bijieensis X.X. Bai & L.Y. Ren, a new species from Northwest Guizhou, China, is here described and illustrated. This new species is distributed discontiguously in Jiulongshan of Dafang County and Dajiucaiping of Hezhang County, both of which belong to Wumeng mountains area, a karst plateau landform. It is morphologically similar to I. lasiophyton J.D. Hooker and I. leptocaulon J.D. Hooker in height, leaf blade shape and flower form, especially resembles I. lasiophyton in pilose plant. However, it differs in its deep purplish-red to rose-red flower, 2-lobed lower sepal apex and cylindrical capsule. A detailed description, color photographs, and a provisional IUCN red list assessment are provided, and its geographical distribution, ecology, and morphological relationship with relevant similar species are discussed.
