Hedysarum (sweetvetch) is a genus of the botanical family Fabaceae, consisting of about 200 species of annual or perennial herbs in Asia, Europe, North Africa, and North America.
Species within genus Hedysarum may be herbaceous plants or deciduous shrubs. They have odd-pinnate leaves, with entire leaflets (no notches or indentations). These leaves resemble the leaves of sweet peas. The stipules may be free or connate, and stipels (secondary stipules) are absent.
The inflorescences are peduncled racemes or heads. Bracts are small, with bracteoles below the calyx, and calyx teeth subequal. The petals may be pink, purplish, yellow, or whitish. Vexillum is longer than the wings, with an obtuse keel longer or rarely shorter than the wings. Stamens are diadelphous, 9+1, and anthers uniform. Ovary is 2-8-ovuled. Fruit is a lomentum, with segments that are glabrous, pubescent, bristly, or spiny, and break into single-seeded sections on ripening
