Abstract
Lespedezajianghuensis (Fabaceae), from Yangtze River basin, China, is described and illustrated as a new species. It is a dwarf shrublet occurring in the riparian meadows along the banks of rivers and lakes. It is morphologically similar to L.cuneata, L.lichiyuniae, and L.caraganae, but differs by its prostrate or decumbent habit, angulate but not furrowed stems, and small stipules (ca. 1 mm). Phylogenetic analyses based on combination of five chloroplasts fragments and ITS sequence confirmed that it belongs to Lespedezasect.Junceae. We also evaluate its conservation status as Least Concern (LC).
