Hemiboea crystallina, a new species of Gesneriaceae from karst regions of Chinaand Vietnam


Phytotaxa 336(1):095-099.

 


ABSTRACT

A new species of Gesneriaceae, HemiboeacrystallinaY.M.Shui& W.H.Chen from China and Vietnam, is described andillustrated. The new species is diagnostic by the combination of its inflated nodes, glabrous stem, glabrous and lanceolateleaves, 4-winged involucre, margin-reflected calyx segments and the glabrous surface inside corolla. Among the specieswithout hairy ring inside corolla, its morphological distinctiveness from the most similar species, H. flaccidaChunex Z.Y.Li, is discussed(Cited from Chen et al., 2018).
