quite glabrous; stipular-spines straight, strong, brown; pinnæ 1–3-jugate, with shield-like glands at most pairs; leaflets 8–15-jugate, oblong, linear, obtuse, thickish; peduncles crowded on abortive ramuli; legume oval, thick, indehiscent, spongy within. A tree, called Kameeldoorn, because the cameleopard browses chiefly on it, but known to the Bichuana natives as the Mokáala. It is much larger than the common karroo-thorn (A. horrida), with a thick and spreading umbrella-shaped head, and thick, brown thorns. The wood is excessively hard and heavy, of a dark, red-brown colour, and used by the Bichuanas for spoons and knife-handles, &c. Burchell, l. c.
