Shrubs, 1-3 m tall, deciduous. Young branches green, densely appressed purple scabrous glandular hairy and white pilose; biennial branches dark gray-brown, densely brown bristly, 2-5 mm. Leaves 15-30 cm; rachis appressed bristly and white curled pubescent, adaxially grooved; petiolule appressed white pubescent; stipel aristiform, persistent; leaflets 5-7(or 8) pairs; leaflet blades elliptic, ovate, broadly ovate, or suborbicular, 1.8-5 × 1.5-3.5 cm, often basal pair of leaflets on rachis smaller, glabrous, abaxially grayish green, adaxially dark red when young but later turning green, midvein abaxially with sparse appressed trichomes, base rounded, apex rounded and aristiform. Racemes axillary, all but corolla appressed purple glandular hairy and white pubescent, 3-8-flowered; peduncle 4-8.5 cm; bracts ovate-lanceolate, 5-6 mm, caducous, sometimes apical ones 3-lobed, apex gradually caudate. Calyx purple, obliquely campanulate; tube ca. 5 mm; teeth triangular, 3-6 mm, apex caudate to subulate. Corolla red to rosy. Petals stipitate; standard subreniform, ca. 2 × 3 cm, apex with a sinus; wings falcate, ca. 2 cm, auriculate; keel nearly triangular, ca. 1.5 cm, apex rounded, connate at leading edge, auriculate. Stamens diadelphous, one opposite to standard free; anthers elliptic. Ovary subterete, ca. 1.5 cm, with densely appressed adenose papillae, faintly pilose along sutures, many ovuled; stigma terminal. Legume linear, 5-8 × 8-12 mm, compressed, 3-5-seeded, with dense appressed bristles, carpopodium short, apex acute. Fl. May-Jun, fr. Jul-Oct.
Cultivated in at least Anhui, Hebei, Henan, Shaanxi, Shandong, Shanxi, and Zhejiang [native to C and E North America].
