Impatiens parvisepala S.X. Yu & Y.T. Hou
Abstract
Impatiens parvisepala S.X. Yu & Y.T. Hou sp. nova (Balsaminaceae), from Guangxi, China, is described and illustrated. It is closely related to I. claviger in having a raceme, yellow flowers and four lateral sepals, but differs by the sessile or subsessile leaves aggregated or subverticillate on the upper part of the stem, obovate or obovate-lanceolate leaf blades, lanceolate or subulate bracts, smaller outer lateral sepals, funnel-shaped lower sepal with a nearly straight spur and reddish patches, and the lateral united petals clawed. Pollen morphology and leaf epidermal characters also support recognition of I. parvisepala.
