Shrub or tree 5–10 m high, generally velvety-villous throughout. Branchlets ribbed, dark coloured. Stipules linear or widely ovate, 3–6 mm long, indurate. Phyllodes narrowly elliptic, 12–17 cm long, 3.6–6 cm wide, unequal at base, acute at apex; indumentum sometimes sparse; midrib prominent and contiguous with lower margin for c. 5 mm above the prominent pulvinus; lateral nerves prominent and openly anastomosing; gland 3–19 mm above pulvinus. Inflorescences 7–10-headed racemes; raceme axes 3–9 cm long; peduncles 2–6 mm long, stout in fruit; heads globular, c. 50-flowered. Flowers 5-merous; sepals c. 2/3-united; petals appressed-puberulous at apices. Pods linear, rounded over seeds and slightly constricted between them, to 18 cm long, 8–9 mm wide, thinly coriaceous.

Hybrids between A. bancroftiorum and A. macradenia resemble A. holotricha but are distinguished by their sparser indumentum.
