Two new species of Hiptage (Malpighiaceae) from Yunnan, Southwest of China

Abstract

Hiptage pauciflora Y.H. Tan & Bin Yang and Hiptage ferruginea Y.H. Tan & Bin Yang, two new species of Malpighiaceae from Yunnan, South-western China are here described and illustrated. Morphologically, H. pauciflora Y.H. Tan & Bin Yang is similar to H. benghalensis (L.) Kurz and H. multiflora F.N. Wei; H. ferruginea Y.H. Tan & Bin Yang is similar to H. calcicola Sirirugsa. The major differences amongst these species are outlined and discussed. A diagnostic key to the two new species of Hiptage and their closely related species is provided.
