A new species of Gesneriaceae, Primulina hunanensis, is described and illustrated from southern Hunnan, China. Morphologically, it is similar to P. cordata (= Chirita cordifolia), but differs by having much larger leaves, broadly ovate or ovate bracts, 2–12 (–25)‐flowers, longer peduncle and purple corolla. It also resembles P. eburnea in the shape of the bracts and the colour of the corolla, but can be distinguished by longer petioles (9–25 cm long), cordate, ovate‐cordate or broadly ovate leaf lamina with rounded or obtuse apex, not entire leaf margin, and either cordate or deeply cordate leaf base. Detailed morphological description, diagnostic comparisons, habitat and micro‐morphology of seeds and pollen under SEM are presented.
