Based on morphological observations and comparisons, a new species of Primulina (Gesneriaceae), P. arcuata G.L.Xu & L.Ding, is described and illustrated. This new species resembles P. jiulianshanensis in leaf blade shape, but differs from the latter by corolla tube curved-tubular (vs. funnelform); calyx lobes oblong (vs. lanceolate); peduncle, pedicel, both surfaces of bracts, both surfaces of bracteoles and abaxial surface of calyx lobes covered with glandular-puberulent hairs (vs. with eglandularpuberulent hairs). A detailed description, photographs, distribution information and a provisional conservation status assessment are provided. [ABSTRACT FROM AUTHOR]

Primulina jiulianshanensis 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).
