Primulinajiulianshanensis F.Wen & G.L.Xu, a new species of Gesneriaceae from Jiulianshan National Nature Reserve of Jiangxi Province, China, is described and illustrated here. Molecular evidence showed it was sister to P.wenii Jian Li & L.J.Yan, while the morphological observation found clear differences between them, petiole, both sides of leaf blades, adaxial surface of the calyx lobes, corolla inside toward the bottom, bract margins covered glandular-pubescent hairs in P.jiulianshanensis ( vs. no glandular-pubescent hairs in P.wenii ); lateral bracts 4-9 × ca. 2 mm, the central one 2-5 × 1-1.5 mm, adaxially glabrous but sparsely pubescent at apex ( vs. lateral bracts 14-16 × 2.5-3.0 mm, the central one 10-12 × 1.3-1.6 mm, all adaxially pubescent); calyx lobes 8-11 × ca. 2 mm, each side with several brown serrate teeth at apex ( vs. 14-15 × ca. 2.5 mm, margin entire); filaments and staminodes sparsely yellow glandular-puberulent ( vs. white, glabrous)., (Guo-Liang Xu, Li-Fen Liang, Di-Ya Chen, Zhi-Fang Jing, Xiao-Hai Zuo, Zheng-Yu Zuo, Fang Wen.)
