Abstract

A new species of the genus Saprosma (Rubiaceae), S. nuichuaensis Q.T.Pham, V.S.Dang & Tagane, from Nui Chua National Park of Ninh Thuan Province, southern Vietnam, is described and illustrated. Saprosma nuichuaensis is closely related to S. ternata, but differs in having terete branches, smaller leaf blades, fewer secondary veins, shorter petioles, smaller calyx lobes, and seeds verrucose on the abaxial side. Photographs, vernacular name and preliminary conservation status are provided.
