Abstract

A new species of Gesneriaceae, Hemiboea crystallina Y.M.Shui & W.H.Chen from China and Vietnam, is described and illustrated. The new species is diagnostic by the combination of its inflated nodes, glabrous stem, glabrous and lanceolate leaves, 4-winged involucre, margin-reflected calyx segments and the glabrous surface inside corolla. Among the species without hairy ring inside corolla, its morphological distinctiveness from the most similar species, Hemiboea flaccida Chun ex Z.Y.Li, is discussed.
