902AD065BF4E50ADA47D93F1EB99DCEA.taxon	diagnosis	Diagnosis. Oreocharis guangwushanensis morphologically resembles O. ronganensis and O. reticuliflora. The new species is vegetatively similar to O. ronganensis, but it differs from the latter in that the adaxial lip is 2 - lobed to or above the middle (vs. lobed to near base), ovary with white pubescence (vs. glabrous), anthers in pairs (vs. anthers free), shorter tube (9 - 14 mm vs. 20 mm), shorter pistil (5 mm vs. 12 - 15 mm) and filaments strongly twisted and bent at the top (vs. linear, straight). The new species resembles O. reticuliflora in habit, flower tube and the shape of the calyx, but differs by its pink limbs (vs. limbs with a network of violet stripes), filaments strongly twisted and bent at the top (vs. linear, straight), anthers in pairs (vs. anthers free), ovary with white pubescence (vs. glandular-pubescence) and shorter pistil (5 mm vs. 10 - 12 mm).	en	Li, Zheng-Long, Ma, Hai-Jun, Ye, Zheng-Rong, Meng, De-Chang, Wen, Fang, Hong, Xin (2022): Oreocharis guangwushanensis, a new species of Gesneriaceae from Sichuan Province, China.
