Morphology General Habit

Tree 8-25 m. high; bark rough, corky, longitudinally furrowed with fibrous strips coming away here and there; young branchlets subglabrous to ± densely short-pubescent.

Morphology Leaves Stipules

Stipules not spinescent.

Morphology General Prickles

Prickles in pairs just below the nodes, straight or recurved, up to c. 1 cm. long, on some twigs few or even apparently absent.

Morphology Leaves

Leaves: petiole often glandular (gland 0·75-1·5 mm. in diam.); rhachis subglabrous to ± puberulous or pubescent, glandular (sometimes interruptedly) between the top 1-4 pairs of pinnae, sometimes with glands at some basal pairs also; pinnae (4)9-14 (? more) pairs; leaflets (8)13-35(45) pairs, (2)4-11(15) x (0·5)1-3(4) mm., narrowly oblong to linear-oblong, slightly ciliolate on the margins and at the base, otherwise glabrous, or wholly glabrous, obtuse to subacute at the apex, with lateral nerves almost or quite invisible beneath.

Morphology Reproductive morphology Inflorescences

Spikes (4)5-11 cm. long, often clustered or several together on short lateral leafless shoots from twigs of the previous year, sometimes opening when the tree is leafless; peduncle 0·3-1·5 cm. long.

Morphology Reproductive morphology Flowers

Flowers sessile.

Morphology Reproductive morphology Flowers Calyx

Calyx purple or reddish-purple, 0·75-1·25 mm. long, cupular, ± puberulous outside.

Morphology Reproductive morphology Flowers Corolla

Corolla coloured as the calyx, 2 mm. long, 5-lobed, ± puberulous outside.

Morphology Reproductive morphology Flowers Androecium Stamens

Stamen-filaments 4-5 mm. long; anthers 0·15-0·2 mm. across, glandular at the apex.

Morphology Reproductive morphology Flowers Gynoecium Ovary

Ovary glabrous, on a stipe half its length.

Morphology Reproductive morphology Fruits

Pods purplish-brown, dehiscent, 11·5-28 x 2·7-3·5 cm., straight, glabrous or almost so; valves thinly woody.

Morphology Reproductive morphology Seeds
