Description:  "Upright tall shrub or small tree 3-5 m high, ?non-lignotuberous. Branchlets with several prominent longitudinal ribs, ± deep red, lenticellate, glabrous. Leaves narrowly elliptic, 8-15 cm long, 4-17 (-27) mm wide, narrowly attenuate, usually acute or acuminate, more rarely obtuse, blackened apically but scarcely mucronate, moderately appressed-sericeous with white and ferruginous hairs when young, rapidly glabrescent; young leaves darker. Involucral buds 3 mm long, subglabrous externally. Inflorescence a single umbel of 16-28 white flowers in upper axils (possibly also on older wood in subsp. angustifolia ); rachis 1-1.5 mm long; pedicels 4.5-7 mm long. Perianth 2-3.5 mm long, glabrous, glaucous; inner surface of tepals sometimes with dense glandular-verrucose covering above ovary. Pistil 6-6.5 mm long. Fruit obliquely ovate, 2.3-3.5 cm long, 1.3-2.3 (-3) cm wide in median view, basally attenuate, with raised black pusticules or 1-5 mm high blunt and black-topped warts; beak smooth or with blunt-topped warts; horns often eroded; red-brown wood zone 2.5 mm wide. Seed 17-20 mm long"  (Flora of Australia online).

"Willow-leaved hakea was introduced for forming hedges and windbreaks but has long been extensively naturalised on the gumlands of N. Auckland. Although still useful, its propensity to naturalise has also made it a noxious weed".
