Abstract
Primulina jiuyishanica K. Liu, D.C. Meng & Z.B. Xin, a new species of Gesneriaceae from Hunan, China, is described and illustrated. The new species is morphologically similar to Primulina fimbrisepala (Hand.-Mazz.) Yin Z. Wang, but differs in its elliptic to broadly elliptic leaf blade with broadly cuneate base, peduncle densely pubescent with sparse glandular hairs, corolla throat with no purple spots inside, the yellow patch in the throat densely glandular-pubescent and pistil densely glandular-pubescent. Photographs and descriptions of the new species are provided below.

Diagnosis: Primulina jiuyishanica resembles P. fimbrisepala (Fig. 2) in having similar inflorescence and corolla color, but can be distinguished by its leaf blade being elliptic to broadly elliptic, base broadly cuneate (vs. blade ovate, broadly ovate to suborbicular, base cordate), peduncle densely pubescent with sparse glandular hairs (vs. eglandular-pubescent to appressed pilose), corolla throat with no purple spots inside (vs. corolla throat with few to many purple spots inside), the yellow patch in the throat densely glandular-pubescent (vs. densely eglandular-pubescent) and pistil densely glandular-pubescent (vs. eglandular-pubescent).
Etymology: The specific epithet is derived from the type locality, Jiuyishan National Nature Reserve, Hunan Province, China.
Vernacular name: 九嶷山报春苣苔(Chinese name);
