An erect or ascending shrub 0.15-2(-5) m tall, from much to rather sparingly branched, with straight, spreading, rigid (rarely rather slender and weak) branches terminating in sharp, leafless thorns, simultaneously representing the inflorescence axes. Young branches yellowish, short-tomentose, ending in naked, glabrous, pointed thorns. Leaflets spreading, from ovoid to linear-subulate, 0.8-4(-6) mm long, terete or angular, often slightly recurved, light green, glabrous, from mucronulate to rather sharply spine-tipped. Inflorescence a 1-5-flowered terminal spike, the axis of which ends in a thorn continuing beyond the most distal flower. Bract narrowly ovate, lanceolate or subulate, 0.5-2.5(-3) x 0.4-1 mm, glabrous on the abaxial side, spine-tipped. Pedicel 1.2-2.8 mm long, pubescent. Bracteoles 0.3-2(-2.7) mm long. Calyx tube either appressedly puberulous or short-ciliate; lobes deltoid to narrowly triangular, 0.27-2.8 mm long, green, spine-tipped. Petals light yellow, bright yellow or orange, the standard sometimes with violet shades. Standard blade 4.8-9.2(-10.6) x 3.8-7.5(-8.7) mm, short-sericeous on most of the back, glabrous on the front, apex ±incurved. Wing blades 2.6-8.5(-10) x 1.3-3(-3.7) mm, glabrous or with some pubescence on lower parts. Keel blades upcurved at almost right angles, 4-8(-8.7) mm long (measured straight from base to apex), 1.8-3. broad at middle, obtuse, upper margin strongly concave, apical-lower half or more short-sericeous. Pistil sericeous on at least up-per half of the ovary and style base. Pod triangular-lanceolate, 5.7-12 x 2.4-4.5 mm, sericeous on most parts.
