|Oreocharis odontopetala Q.Fu & Y.Q.Wang|
in Fu, Xia, Guo, Huang & Wang, 2019.
A new species, Oreocharis odontopetala Q.Fu & Y.Q.Wang from Guizhou Province in southwest China, is described and illustrated, based on morphological comparison with existing species. It is morphologically most similar to O. elegantissima, but can be easily distinguished by its adaxially bullate leaf blade, abaxially conspicuous reticulate veinlets, brown-purple peduncles, triangular adaxial corolla lobes and abaxial corolla lobe margins bearing 4–10 long teeth, glabrous style and shorter stamens with confluent thecae at the apex, as well as leaf epidermal characters.

Oreocharis odontopetala Q.Fu & Y.Q.Wang, sp. nov.
Diagnosis: Oreocharis odontopetala is most similar to O. elegantissima, having a similar shape of leaf blade, lanceolate sepals and bracts, stellate ring-like disc, pistil and fruits. Oreocharis odontopetala differs from O. elegantissima by its adaxially bullate leaf blade (vs. not bullate), with abaxially reticulate veinlets conspicuous (vs. veinlets inconspicuous); peduncles brown-purple (vs. green); adaxial corolla lobes triangular (vs. oblong) and abaxial corolla lobe margins with 4–10 long teeth (vs. margin nearly entire); style glabrous (vs. glandular pubescent) and stamens shorter (adaxial 0.5–1.4 vs. 2.0–2.6 cm, abaxial 0.8–1.8 vs. 2.3–2.7 cm) with confluent thecae at apex (vs. not confluent).
Etymology: The species is named after its abaxial strongly toothed corolla lobes.
Vernacular name: Chǐ Bàn Cū Tǒng Jǜ Tái (Chinese pronunciation); 齿瓣粗筒苣苔 (Chinese name).
