D7BA8BE6ADF7542EA75E02E712C5799E.taxon	diagnosis	Diagnosis. L. jianghuensis is morphologically most similar to L. cuneata, in having narrow leaflets and straight lateral veins to the margin, but differs from the latter by its prostrate or decumbent habit (vs. erect or ascending), stems strongly branched at the base (vs. stems simple), branches with appressed-pubescent (vs. densely ascending-pubescent), leaves sparse (vs. leaves crowded), leaflets narrowly obovate, terminal leaflets 5 – 16 mm long (vs. cuneate or linear-cuneate, terminal leaflets 7 – 30 mm long in L. cuneata), abaxial surfaces of leaves pubescent with obvious veins (vs. densely whitish pubescent, veins indistinct), stipules triangular, 0.7 – 1 mm long (vs. lanceolate, 1 – 4 mm long in L. cuneata) and calyx lobes narrowly triangular (vs. lanceolate) (Fig. 5).	en	Huang, Song, Chen, Mei-Qian, Song, Feng, Li, Jia-Xiang, Pan, Bo, Zhong, Hui-Yi, Zhou, Li-Qun, Liu, Ang, Zheng, Yu-Tao, Zhao, Pan (2025): Lespedeza jianghuensis (Fabaceae), a new species from riparian meadows of Yangtze River basin, China.

D7BA8BE6ADF7542EA75E02E712C5799E.taxon	distribution	Geographical distribution and habitat. Lespedeza jianghuensis is widely distributed in the middle reaches of Yangtze River basin in China (Fig. 6). such as Hunan, Jiangxi and Hubei Provinces. It grows on river floodplains, lakeshore terraces, mudflats, marshes, headlands, and other grasslands and wastelands close to rivers and lakes at elevation from 7 to 39 meters, and it is subject to seasonal flooding in summer.	en	Huang, Song, Chen, Mei-Qian, Song, Feng, Li, Jia-Xiang, Pan, Bo, Zhong, Hui-Yi, Zhou, Li-Qun, Liu, Ang, Zheng, Yu-Tao, Zhao, Pan (2025): Lespedeza jianghuensis (Fabaceae), a new species from riparian meadows of Yangtze River basin, China.
