Morphology General Habit

An often tall liane; young branchlets sparsely puberulous to glabrous and eglandular, very rarely with inconspicuous sessile glands, red-brown to deep purplish.

Morphology General Prickles

Prickles deflexed, scattered, arising from longitudinal bands usually darker than the intervening ones.

Morphology Leaves

Leaves: petiole (1·5)2-6 cm. long; pinnae 8-15 pairs, 2·5-9 cm. long; leaflets 0·7-1·8(2) mm. wide, linear or linear-oblong, glabrous or nearly so; midrib nearer one margin at the base.

Morphology Reproductive morphology Flowers

Flowers white, in heads 8-10(12) mm. in diam. usually in ample panicles.

Morphology Leaves Stipules

Stipules at base of peduncles small, 0·75-1·5 mm. wide, inconspicuous, soon caducous, not subcordate at the base.

Calyx eglandular outside.

Morphology Reproductive morphology Flowers Corolla

Corolla glabrous or rarely sparingly puberulous outside.

Morphology Reproductive morphology Fruits

Pods thick, hard, dark-brown, indehiscent, 7·5-16 x 1·8-3·5 cm., oblong, with markedly thickened margins 2-4 mm. wide.

Morphology Reproductive morphology Seeds
