摘要

报道了中国长江流域一新种胡枝子（豆科）。它是一种矮灌木，生长在河流和湖泊沿岸的河岸草地上。它在形态上与L.cuneata、L.lichiyuniae和L.caraganae相似，但不同之处是其匍匐或平卧习性、成角但不具沟状的茎和小托叶（约1毫米）。基于5个叶绿体片段组合和ITS序列的系统发育分析证实该植物属于胡枝子科（Lespedezasect.Junceae）。并评价其保护现状为最不关注（LC）。

Lespedezajianghuensis (Fabaceae), a new species from riparian meadows of Yangtze River basin, China.

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).
