Abstract
Cardaminezhangjiajieensis, a new species from Hunan Province, China, is described and illustrated. Cardaminezhangjiajieensis is similar to C.circaeoides. From the latter, C.zhangjiajieensis is readily distinguished by the terminal leaflet of the cauline leaf 4.5-7 cm (vs. 2.5-4.5 cm), mostly round or oblong (vs. oblong-oval to triangular-oval), margin undulating sinuses (vs. crenate or subentire), seed apically narrow wing (vs. wingless).
