Abstract

Hydrocotyle changanensis X.C. Du & Y. Ren sp. nova (Araliaceae) is described from Shaanxi Province, northwestern China. The simple scapes of H. chonganensis have 2–5 layers of flowers in their umbels, different from all other Chinese Hydrocotyle species. It is morphologically similar to H. sibthorpioides, however it differs from the latter by its narrower and longer styles, depressed stylopodia and longer pedicels. We present a key for identification, a line drawing of H. chonganensis and a plate of SEM micrographs of H. changanensis and H. sibthorpioides. We discuss the relationships among H. changanensis and all species currently recognized in this genus in China.
