   Acacia Catechu is a small-sized tree, from 15 to 20 feet high. The bark is thick, scabrous, rust-colored, slightly bitter, and exceedingly astringent; the branches are spreading, armed with strong, black, stipulary spines, and downy toward their extremities. The leaves are bipinnate; pinnae 10 to 20 pairs; leaflets 30 to 50 pairs, linear, bluntish, unequal, and auricled on the lower side of the base, and ciliated; the petiole angular, and channeled above, downy, with 1 orbicular urceolate green gland below the lowest pair, smaller ones between the two, and has 3 or 4 terminal pairs of pinnae. The spikes are axillary, 1 or 2 together, slender, cylindrical, and borne on downy stalks. The flowers are numerous, white or pale-yellow, and sessile. The calyx is downy, tubular, and 5-toothed; the teeth erect. Corolla rather longer than the calyx, 5-petaled, and glabrous. Stamens twice the length of the corolla, very numerous and distinct, anthers roundish. The ovary is green, glabrous, and shortly stipitate; the style capillary, and as long as the Stamens; stigma simple.
