﻿AbstractPrimulinajiulianshanensisF.Wen & G.L.Xu, a new species ofGesneriaceaefrom Jiulianshan National Nature Reserve of Jiangxi Province, China, is described and illustrated here. Molecular evidence showed it was sister toP.weniiJian 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 inP.jiulianshanensis(vs.no glandular-pubescent hairs inP.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).
