Abstract

Paraboea crassifila, a new species of Gesneriaceae from Danxia landform in Guangxi, China is described and illustrated, based on morphological and anatomical features. Paraboea crassifila sp. nov. is reported firstly from Danxia landform in China, with the special feature of enlarged filaments differing from the others of Paraboea distributed in China. Paraboea crassifila is similar to Paraboea guilinensis L. Xu & Y.G. Wei in the habit, but it can be distinguished by the obovate to narrowly obovate leaf blade, the peduncle and calyx covered with ferrugineous matted indumentums, the corolla arachnoid outside, the enlarged filaments, and 3 staminodes.
