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, 7–17 (–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.
Distribution and ecology
Widespread on the coast and ranges of N.S.W. from the Qld/N.S.W. border south to Jervis Bay, extending to Springbrook in the Macpherson Ra. in south-eastern Qld. Occurs in wet sclerophyll forest.
Naturalised in the Melbourne area as early as the 1880s, in the Adelaide Hills, S.A., on Norfolk Is., N.S.W., the North Island of New Zealand and Cape Town, South Africa.

Derivation of name
From Salix, the genus for willow and folius, Latin for leaf, a reference to the willow-like leaves of this species.
How the infraspecific taxa differ
Subsp. salicifolia and subsp. angustifolia, as the latter name suggests, differ in the width of the leaves; subsp. salicifolia has leaves 7-27 mm wide while those of subsp. angustifolia are 4-7 mm wide. Subsp. angustifolia is confined to the river systems of the Sydney region while subsp. salicifolia is much more widely spread in wet sclerophyll forest on the eastern coast line of New South Wales.
Part of Section Hakea of Bentham (as Euhakea) and characterised by a non-conical pollen presenter, leaves without obvious venation, perianths with or without hairs and fruits with or without horns. Barker et al. (1999) recognised a number of informal morphological groups within the section.
H. salicifolia was treated as part of the Salicifolia group, an eastern states group characterised by their simple flat leaves, few-flowered inflorescences, glabrous pedicel and perianth and erect fruits, these markedly verrucose or pusticulate and usually with horns.
The only members of this group are H. florulenta and H. salicifolia.
