FFB736EB761B5A03AD01E88F2AA8A251.taxon	diagnosis	Diagnosis. Oreocharis corallodiscoides is similar to O. agnesiae (Forrest ex W. W. Sm.) Mich. Möller et W. H. Chen in texture and indumentum of the leaves, as well as in flower morphology and size, but can be clearly distinguished from the latter by its leaves ovate, rounded or sometimes rhombic (vs. ovate to oblong), with a length-to-width ratio of 1 – 1.5 (vs. 2.2 – 2.7), corollas yellow (vs. purple-red), and the presence (vs. absence) of two purple and triangular appendages inside the base of the corolla tube. Additionally, while O. corallodiscoides shares the inflated yellow corolla tube with O. longifolia, it differs by its ovate-rotund leaves (vs. lanceolate-oblong), shorter petioles (0.5 – 2 cm vs. 3.5 – 5 cm), crenate leaf margins (vs. serrate), glandular pistils (vs. glabrous), and the presence of appendages with thickened filaments.	en	Li, Xi, Wang, Qiu-Ping, Yang, Feng, Ye, Jing-Yi, Wang, Huan-Chong (2025): Oreocharis corallodiscoides (Gesneriaceae, Trichosporeae, Didymocarpinae), a new species from Yunnan, southwest China.

FFB736EB761B5A03AD01E88F2AA8A251.taxon	etymology	Etymology. The specific epithet corallodiscoides is derived from the generic name Corallodiscus Batalin (Gesneriaceae) by adding the suffix “ - oides ”, reflecting the leaf morphological similarity of this new species to some members of the genus Corallodiscus, such as C. lanuginosus (Wall. ex A. DC.) B. L. Burtt; particularly, its sometimes rhombic leaves are rare in the genus Oreocharis.	en	Li, Xi, Wang, Qiu-Ping, Yang, Feng, Ye, Jing-Yi, Wang, Huan-Chong (2025): Oreocharis corallodiscoides (Gesneriaceae, Trichosporeae, Didymocarpinae), a new species from Yunnan, southwest China.

FFB736EB761B5A03AD01E88F2AA8A251.taxon	distribution	Distribution and ecology. Oreocharis corallodiscoides is known only from Xiaoluzhi village in the Luzhijiang valley, Yimen county, Yunnan province, southwest China. Its habitat is characterized by seasonally hot and arid conditions, occurring on dry slopes within the valley (Fig. 3). The species is typically found in limestone grasslands at elevations ranging from 1,300 to 1,400 meters, where water availability is limited. Additionally, Oreocharis corallodiscoides often grows together with Corallodiscus lanuginosus (Wall. ex A. DC.) B. L. Burtt, and interestingly, these two species of different genera have very similar leaf shapes and indumentum (Fig. 3 B).	en	Li, Xi, Wang, Qiu-Ping, Yang, Feng, Ye, Jing-Yi, Wang, Huan-Chong (2025): Oreocharis corallodiscoides (Gesneriaceae, Trichosporeae, Didymocarpinae), a new species from Yunnan, southwest China.
