Abstract

Based on morphological, cytological and molecular data, a new species of Gesneriaceae, Petrocodon jiangxiensis F. Wen, L.F. Fu & L.Y. Su from Jiangxi Province, China, is described and illustrated. Morphologically, it resembles the most P. asterocalyx. Both species have axillary cymes, an actinomorphic calyx and similarly shaped corolla, but P. jiangxiensis can be easily distinguished by ovate-elliptic to broadly ovate leaf blades, three bracts with a crenulate to serrate margin, smaller calyx lobes 5–6 × ca. 1 mm, smaller corolla 1.7–2.3 cm long, and glabrous anthers. Petrocodon jiangxiensis has a 2n = 36 somatic chromosome number.
