Summary
A dense, glabrous, spreading light–green shrub, Acacia pinguifolia grows 1–2 m in height and often 2–3 m across. Numerous terete, ascending, arching branches extend from just above or at ground level, with branchlets glabrous, smooth, reddish–brown and with thin bark which is pale grey at the base of the stems. Phyllodes are 1–3.5 cm long, 2–3 mm in diameter and are straight or falcate, terete or somewhat compressed, rigid, thick and fleshy and light green in colour. The surface of phyllodes becomes wrinkled and grooved when dry and the apex ends abruptly with a minute, hard, thick point (Jessop and Toelken 1986).
Inflorescences are simple and axillary, solitary or twin, or sometimes up to four heads. Flower–heads are globular, deep yellow, with 20–30 individual flowers. Peduncles are glabrous, 5–10 mm long and legumes are 5–7 cm long, 5 mm broad, curved and finally twisted, swollen and raised over the seeds, dark brown with light–brown margins and are slightly constricted between the seeds. The seeds are longitudinally arranged within the legume, ellipsoid in shape with a whitish, fleshy aril (Jessop and Toelken 1986).
