    Glabrous shrub up to 3 m. tall; branches purplish when young, sulcate, with 3-partite spines up to 4 cm. long.
    Leaves
    Leaves usually clustered on short lateral shoots, almost sessile, apparently simple but in reality 3-foliolate with a normal, terminal leaflet articulated at its base and a petiole of c. 1 mm. long bearing 2 subulate lateral leaflets 1–3 mm. long at its apex. The petioles and subulate leaflets are characteristically persistent on the short shoots; lamina of terminal leaflet up to 6 x 2.7 cm., coriaceous, oblong or oblanceolate to obovate, midrib produced as a short prickle, margin prickly-dentate or more rarely entire, purplish when young and somewhat glaucous below.
