Genus Novum Gesneriacearum e Vietnam (“A New Genus of Gesneriaceae from Vietnam”)

In 1926, based on a specimen (Poilane 3846) collected from Vietnam, F. Pellegrin described a new species of the genus Hemiboea. Recently, after dissecting a flower of the holotype we realized that this species was erroneously placed in Hemiboea, differring from the latter in a series of important morphological characters, and in fact represents a new genus (Deinostigma) of the tribe Didymocarpeae, and is described in the present paper as Deinostigma poilanei.
