Morphology General Habit
A shrub or tree 2-10 m. high, not climbing; bark rough, scaly, dark-grey to brown; young branchlets varying from subglabrous with a little puberulence to densely spreading-pubescent or even (though not in our area) tomentose.
Morphology Leaves Stipules
Stipules not spinescent, subulate-linear.
Morphology General Prickles
Prickles in pairs just below the nodes, patent to ± hooked, up to 7 mm. long, often sparse; occasionally with a few additional prickles scattered elsewhere on the stem.
Morphology Leaves
Leaves: petiole (1)1·3-3·5 cm. long; rhachis 3-19 cm. long, prickly or unarmed; gland on petiole present or absent, 0·75-1·75 mm. long, also with glands between top 1-4 pairs of pinnae; pinnae (4)6-27 pairs; leaflets 13-57 pairs, 2-7(10) x 0·6-1·5(2·5) mm., glabrous or with some appressed or spreading cilia on the margins or (but not in our area) densely hairy on the margins and ± so on the lower surface, rounded to obtuse at the apex, with midrib and often also lateral nerves usually rather prominent beneath.
Morphology Reproductive morphology Flowers
Flowers creamy-yellow to white, sessile, in spikes (2)4-10 cm. long on peduncles (0·5)1-3 cm. long; axis ± densely puberulous to pubescent or tomentose, also glandular.
Morphology Reproductive morphology Flowers Calyx
Calyx 2-3 mm. long, rather densely puberulous to pubescent, 2/3-5/6 as long as the corolla.
Morphology Reproductive morphology Flowers Corolla
Corolla 2·5-3·5 mm. long, ± puberulous to pubescent on the outside of the lobes.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamen-filaments 6-7 mm. long; anthers 0·15 mm. across, with a caducous gland.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary glabrous, shortly stipitate.
Morphology Reproductive morphology Fruits
Pods brown, dehiscent, 6-17 x 0·9-1·5(1·9) cm., puberulous, rarely pubescent, and with sparse to dense reddish-brown glands over the surface, linear, straight to ± curved, acute to attenuate at the base and apex.
Morphology Reproductive morphology Seeds
Seeds 8-10 x 7-8 mm., flattened; central areole small, 2-3 x 2-2·7 mm.
