F27611A2C2F55DBCA467C6E8981E10AD.taxon	diagnosis	Diagnosis. This species is similar to D. basilare, D. trifoliolatum, D. carinatum, D. franchetii, D. adiantifolium, and D. arisanense. However, it differs from these species in several key morphological traits. Specifically, its leaflets are scalloped or suborbicular (vs. rhombic to broadly rhombic-ovate in the other six species), and its inflorescence bears only a single flower (vs. 3 – 7 flowers in the inflorescences of the other species). Additionally, it differs from D. uniflorum, which also features a single flower, in terms of leaflet quantity and flower size.	en	Wang, Bo, Wang, Ze-Huan, Xu, Wen-Fen, Li, Yun-Chao, Lu, Xiang, Sun, Qing-Wen, He, Shun-Zhi (2025): A new Dichocarpum W.

F27611A2C2F55DBCA467C6E8981E10AD.taxon	distribution	Distribution and ecology. The new species is currently restricted to the type locality, specifically Kaoru Mountain, located in Kaika Village, Wantanhe Township, Longli County, Guizhou, China, at an approximate elevation of 1139 meters. Here, only three populations comprising approximately 120 individuals were discovered growing in a moist gully and the entrance of a cave. These plants were accompanied by Adiantum capillus-veneris Linnaeus (Pteridaceae), Hymenasplenium sp. (Aspleniaceae), Elatostema sp. (Urticaceae), and other species.	en	Wang, Bo, Wang, Ze-Huan, Xu, Wen-Fen, Li, Yun-Chao, Lu, Xiang, Sun, Qing-Wen, He, Shun-Zhi (2025): A new Dichocarpum W. T. Wang & P. K.
