Abstract

A new species, Trigonostemon honbaensis Tagane & Yahara (Euphorbiaceae), sp. nov., from Hon Ba Nature Reserve in Khanh Hoa Province, southern Vietnam, is described and illustrated. DNA barcoding data of the rbcL and matK regions is provided. Trigonostemon honbaensis is most similar to T. longifolius Baill. ex Müll.Arg., but distinguished by its less hairy leaves, truncate leaf base (attenuate to obtuse in T. longifolius), larger petals, shorter staminal column, and anthers lacking appendages.
