 Description

Shrub, up to 3(-8) × 2-3 m. Branches up to 100 mm diameter, ascending and horizontal. Cladodes 40-250 × 1-2.3 mm, erect and spreading, often divaricate, linear, striate, compressed, green, frequently hairy when young, glabrous when mature, apex subacute; leaf nodes 5—14(—19) mm. Leaves 1—7-foliolate, present on seedlings and adults, terminal leaflet larger; lamina 2-13 × 1-8(-13) mm, obovate to broad-elliptic, rarely orbicular, fleshy, green, adaxial and abaxial surfaces hairy or glabrous, apex emarginate, base cuneate; petiole 5—25 mm long, glabrous or hairy, green; petiolule < 0.3 mm long, glabrous or hairy, light green. Leaves on cladodes reduced to scales, < 0.8 mm long, broad-triangular, glabrous, apex acute. Stipules c. 1 × c. 1 mm, free, triangular, adaxial surface glabrous, abaxial surface hairy, apex subacute, margin hairy. Inflorescence a raceme, 1 per node, each with (4—)8-40 flowers. Peduncle 4— 10 mm long, glabrous, green. Bracts < 0.8 mm long, triangular, glabrous, brown, apex acute to subacute, margins hairy. Pedicel c. 1 mm long, glabrous, green. Bracteoles < 0.5 mm long, at top of pedicel or on receptacle, green and sometimes flushed red, glabrous, apex obtuse, margin hairy. Calyx 1.5-2 × 1— 1.2 mm, campanulate, green, outer surface glabrous. Calyx lobes 0.2—0.3 mm long, triangular, green and usually flushed red, inner surface hairy, appressed to corolla, apex subacute to obtuse. Standard 3.5-4 × 2.5-3.5 mm, broad-obovate, patent, positioned towards front of keel, keeled, apex emarginate, margins flattened; central part of inner and outer surfaces purple or red-purple, margins white, sometimes purple-veined; claw c. 1 mm long, pale green. Wings 3.5—4 × 0.9—1.1 mm, oblong, similar in length to keel, inner and outer surfaces white, sometimes purple-veined, apex obtuse; auricle 0.2-0.4 mm long, triangular, white, apex obtuse; claw 1.3— 1.5 mm long, pale green. Keel (Fig. 2D) 3.5-4 × 1.4— 1.7 mm, apex obtuse; distal area of inner surface purple, proximal area white; outer surface white, flushed purple in distal part and sometimes purpleveined; auricle 0.2—0.4 mm long, triangular, white, apex obtuse; claw 1.3—1.5 mm long, pale green. Stamens 3.5-4 mm long; dorsal filaments connate for c. 7/8 of length, outer stamens free for 0.2—0.5 mm. Pistil 3.7-4.2 mm long, exserted beyond stamens, glabrous; ovules 4-9(—11). Pods 5-9 × 1.5-3 mm, oblong, broad-elliptic or ovate, laterally compressed, erect, light grey or brown, valves dehiscent in distal part; beak 1-2.5 mm long, in a central apical position, stout, pungent-tipped. Seeds 2-3.7 × 1.6— 2.4 mm, broad-oblong to broad-elliptic, 1-3 per pod, laterally compressed, surface with 1—3 ridges, testa thin and membranous, light brown or tan.
