Dense, glabrous, spreading, light green shrubs 1-2 m high and often 2-3 m across with numerous, terete, ascending, arching branches from just above or at ground level; branchlets glabrous, smooth, reddish-brown; bark thin and pale grey at base of stems.

Phyllodes 1-3.5 cm long, 2-3 mm diam., straight or falcate, terete or somewhat compressed, rigid, thick andfleshy, light green, sub-sessile, veins longitudinal,10-15 rather obscure due to surface becoming wrinkled and grooved when dry, apex ending with a small hard thick mucro.
