A small deciduous tree, said to be 40 ft or more high in the wild, with peeling bark, but usually shrubby in cultivation in this country; young shoots minutely downy. Leaves 8 to 12 in. long, pinnate, with seven to eleven leaflets; the main-stalk rather swollen at the base, but leaving the bud quite exposed; leaflets opposite, ovate, blunt at the top, 11⁄2 to 3 in. long, dark green above, paler and glabrous beneath. Flowers borne in July and August, pea-shaped, dull white, closely set on stiff, erect racemes, 4 to 6 in. long, sometimes branched at the base. Each flower is 1⁄2 in. long on a short stalk about half its length; calyx bell-shaped, 1⁄6 in. long. Pods 2 to 3 in. long, 1⁄3 in. wide, flat, with the seam slightly winged.

Native of Manchuria; introduced in 1864. An example at Kew, pl. 1922, measures only 15 × 11⁄4 ft (1968).
