Phyllodes oblanceolate to narrowly oblong or elliptic, 4-9 cm long, 7-14 (-16) mm wide, obtuse with a blunt apiculum, coriaceous, silvery grey-green, sericeous between nerves, with 1 or 3 distant main nerves per face and numerous fine closely parallel non-anastomosing nerves in between; central nerve slightly more prominent than the rest; marginal nerves yellow (reddish and resinous on young phyllodes). Inflorescences simple, 1-headed; peduncles 2-3 (-5) mm long, sericeous, with indumentum often obscured by resin; spikes obloid to short-cylindrical, 7-10 mm long, 4-5 mm diam., light golden. Flowers 5-merous; sepals 2/3-3/4-united, with broadly triangular lobes. Pods erect to patent, linear, straight, to 10 cm long, 4-5 mm wide, firmly crustaceous, hoary.
