Abstract

A new species of Helicteres (Malvaceae), H. daknongensis V.S.Dang & D.T.Bui from Gia Nghia district, Dak Nong province, southern Vietnam, is described and illustrated. This species is morphologically similar to H. viscida Blume and H. hirsuta Lour. but differs by having smaller petals and fruits, and different petal colour. A morphological description, photographs and a table comparing the new species with its closely related species are provided, as well as an updated key to Helicteres in Vietnam.
