Abstract


Oreocharis uniflora, a new species of Gesneriaceae from Guangdong, China, is described and illustrated. The new species is morphologically similar to O. striata and O. lungshengensis, but differs mainly by its white villous leaf blades and petioles, 1-flowered cymes, shorter peduncles (1.8–3.5 cm long), 3–5-serrate calyx lobes, pale purple to reddish purple corollas, inside with longitudinally purple striations, campanulate-tubular corolla tubes, 4 free stamens, and 1 disc-shaped stigma. Based on the current information, O. uniflora should be considered as ‘Critically Endangered’ (CR), following the IUCN categories and criteria.
