DED001027E8A51AB88F745C6D83341AB.taxon	diagnosis	Diagnosis. This new species is similar to C. macrophylla Willd., but it differs in the following characteristics: more prominent tubers, shorter plant height (10 – 25 cm vs. 20 – 115 cm), fewer cauline leaves (3 – 4 vs. 3 – 18), distinctly petiolulate leaflets (vs. sessile or occasionally with a short petiole), crenate leaf margin (vs. serrate), fewer flowers (4 – 10 vs. 10 – 30), white flowers (vs. purple or lilac, rarely white), an earlier flowering period (late February to mid-March vs. April to June) and shorter growth cycle in one year (ca. 3 months vs. ca. 8 months) (See Fig. 4, Table 1).	en	Liu, Ang, Li, Xiong, Deng, Guo-xing, Chen, Jun, Liu, Zan, Yu, Xun-Lin, Wu, Lei (2025): Cardamine mangshanensis, a new species of Brassicaceae from limestone landform in Southern Hunan, China.
