Abstract
Based on morphological observation and literature consultation, a new species of Oreocharis (Gesneriaceae), O. reticuliflora Li H. Yang & X.Z. Shi, is described and illustrated. This new species resembles O. auricula, but differs by its conspicuous and reticular secondary veins, corolla with a network of violet stripes on each lip lobe, glandular-pubescent ovary, shorter capsule and being densely brown woolly on the abaxial leaf surface, outside of bracts and calyx lobes. A detailed morphological description and photographic illustration of the new species are presented.

Oreocharis reticuliflora Li H. Yang & X.Z. Shi, sp. nov.
A species that mainly differs from Oreocharis auricula (S. Moore) C.B. Clarke by its conspicuous and reticular secondary veins on the abaxial leaf surface (versus inconspicuous), corolla with a network of violet stripes on each lip lobe (versus without such color pattern), glandular-pubescent ovary (versus glabrous), shorter capsule (ca 2 cm long versus ca 4.5 cm long) and by being densely brown woolly on the abaxial leaf surface, outside of bracts and calyx lobes (versus sparely brown villous).
Etymology: The specific epithet, reticuliflora, is derived from the Latin words, reticulum and flora, referring to the network of violet stripes on corolla limb of this new species.
Vernacular name: In Chinese mandarin ‘Wang Wen Ma Ling Ju Tai' (网纹马铃苣苔).
