leaflets in 6–8 pairs, sub-equal, obtuse; peduncle in the axil of the 2–3 times shorter leaf; petals nearly thrice as long as the calyx; stigma pyramidal, twice as long as the short style; carpels with 4 spines and prickly at back. Nearly allied to the preceding, especially to var. γ., with which it agrees in the silky-canescent leaves and smaller fruits, but differs in the peduncles twice as long, larger petals and stigma. Stems weak, 1–2 feet long, villous or glabrescent. Stipules ovato-lanceolate. Leaves unequal, one uncial, the other (from whose axil the peduncle springs) thrice as short. Leaflets 1 1/2–2 lines long, green above. Peduncles uncial. Sepals ovato-lanceolate, appressedly silky. Petals cuneate, 5–6 lines long. Style twice or thrice as short as the stigma, stigma 1 line long. Fruit smaller than a pea; the spines mostly unequal, the larger nearly 1/2 line long; tubercles numerous, hard, acute or sub-spinulous, mostly hairy.
