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.

Webb, C. J./Sykes, W. R./Garnock-Jones, P. J. (1988) (p. 999)
"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".
