A new species of Claoxylon (Euphorbiaceae), C. langbiangense, from Bidoup-Nui Ba National Park, Lam Dong Province, southern Vietnam, is described and illustrated. It resembles C. longifolium of Cambodia, NE India, Indonesia, Laos, Malaysia, Papua New Guinea, Thailand and Vietnam, but is distinguished by its serrate-dentate leaf margin, larger staminate flowers and shorter pistillate inflorescences. A vernacular name, preliminary conservation status for the species, and a key to the species of Claoxylon in Vietnam is also provided.
