Impatiens liupanshuiensis (Balsaminaceae), a new species from Guizhou, China
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.
