Henckelia longisepala (H.W.Li) D.J.Middleton & Mich.Möller is reported from Lai Chau and Nghe An provinces of Vietnam as a new national record of the species. An amended morphological description and photographic illustrations are provided. The distribution of H. longisepala is discussed with an emphasis on the floristic regions inhabited by this species. A specimen at KUN is selected for a second-step lectotypification. Two floral morphologies were found in H. longisepala that differ in the length of the pistil and its significance is discussed here.
