Cladodes linear, striate, compressed, erect to spreading, green, glabrous, often crowded at ends of branches, 60-220 × 1.5- 2.5 mm; apex subacute, yellow; leaf nodes 4-9. Leaves 1-9-foliolate, fleshy, obovate or sometimes ovate, hairy; adaxial surface mottled; abaxial surface green; apex emarginate to retuse; margin hairy; leaflets sessile or with short petiolule, 1.5-7 × 1-6.5 mm; petiole hairy, 8-16 mm long. Leaves on cladodes reduced to a scale, triangular, glabrous, < 0.5 mm long; apex acute. Stipules clasping shoot, triangular, 0.4-0.5 × 0.4-0.5 mm; adaxial surface glabrous; abaxial surface hairy, becoming glabrous with age; apex subacute to obtuse; margin hairy. Inflorescence a raceme, 1 per node, each with (3-)5-6 flowers. Peduncle glabrous to sparsely hairy, green, 7-16 mm long. Bracts triangular to narrow-triangular, pale green becoming membranous, 0.5-1 mm long; apex acute to subacute; margin hairy. Pedicel glabrous, pale green, 2-A mm long. Bracteoles at base of receptacle or on upper part of pedicel, narrow- triangular, green and flushed red, glabrous, 0.4—0.8 × 0.1-0.3 mm; apex acute; margin hairy. Calyx campanulate, c. 1.5 × c. 1 mm; inner and outer surfaces glabrous, green, usually flushed with red. Calyx lobes triangular, flushed red, c. 0.5 mm long; apex acute; margin hairy. Bud white to pale purple. Standard obovate, spreading above wings and keel, 3—4 × 3.5^4.5 mm; adaxial surface purple, purpleveined; abaxial surface white, purple-veined; apex retuse; margin recurved; claw pale green, c. 1 mm long. Wings oblong, longer than keel, c. 4 × c. 1 mm; adaxial and abaxial surfaces white, distal area flushed purple, sometimes purple-veined; auricle rounded, white, c. 0.3 × c. 0.3 mm; claw pale green, c. 1 mm long. Keel (Fig. IB) c. 4 xc. 1.5 mm; distal area of adaxial and abaxial surfaces purple, central area white, and proximal area pale green; auricle rounded, white, c. 0.25 mm long; claw pale green, c. 2 mm long. Stamens 3-3.5 mm long; lower filaments connate for c. 7A length and with outside filaments free for 0.3-0.5 mm. Pistil exserted beyond stamens, c. 4 mm long; style with a ring of hairs below stigma; ovules 6-7. Pod obovate, broad at distal part, dorsally compressed, brown, pale grey, or straw-coloured, indehiscent, with inflated valves, 5-5.5 × 3-4 mm; beak on upper suture, slightly curved, stout, pungent, c. 1 mm long.
