Deciduous, rather spreading, ± dense shrub 1-2.5 m high, often with suckers; stems often rather arching, especially on young plants, glabrous or nearly so; armature of numerous, mostly rather uniform, flattened, moderately to strongly falcate prickles, with acicles only on petioles and lf rachises. Lvs with 2-3 pairs of leaflets; petiole 15-25 mm long, with few to many glandular hairs; stipules completely adnate, entire except for numerous dark red marginal glandular hairs, otherwise stipules glabrous.

Fls 1-5-(7), single, 25-30-(40) mm diam.; pedicels with many hispid glands. Sepals ± deciduous, lanceolate to ovate, long-acuminate, tomentose inside, with glandular hairs outside and on margins, sometimes puberulent, especially towards margins; outer sepals pinnatisect with a few linear lobes. Petals c. 12-15-(20) mm long, obovate, pink in bud, pale pink or whitish at anthesis. Styles free, shortly exserted, glabrous or glabrate.
