Oreocharispolyneura, a new species of Gesneriaceae from southern Yunnan, China.

Oreocharispolyneura, a new species from southern Yunnan, China, is described and illustrated. It is morphologically similar to O.rhytidophylla by having more obvious lateral veins forming a crosslinked network on the adaxial surface of leaf blades, but can be distinguished by having more lateral veins (12-15 pairs vs. 7-9 pairs) of leaf blades, shorter corolla tubes (the length ratio of corolla tube to corolla lobes = 1.2-2.9 vs. 3.4-6) and shorter pistils (6-8 mm long vs. 27-30 mm long). In addition, a detailed morphological description, a photographic illustration, the distribution and phenology of the new species are presented.
