Abstract:Stephania brevipes Craib (Menispermaceae), previously known only from Thailand is reported from Vietnam for the first time. It is morphologically allied to S. longa Lour., but differs in having broadly triangular-ovate to triangular-oblate leaves, a small male inflorescence axillary or on leafless stems with shorter peduncle, yellowish sepals, red-violet petals, and endocarps with fewer transverse ridges. A detailed morphological description, a line drawing and color plate as well as distribution and ecology information of this species are given. The vouchers are kept in the herbaria of Vietnam National Museum of Nature (VNMN) and South China Botanical Garden, Chinese Academy of Sciences (IBSC).
