Erect, much-branched or compact and spreading shrub, 1–4 m tall. Young axillary branchlets densely tomentose, some hairs appressed; hairs white or dirty brown; terminal branchlets more quickly glabrous, while remaining densely pubescent at their base, glabrescent by flowering. Leaves rigid, terete, sometimes flattened when young, 0.5–7.7 cm long, 0.8–1.7 mm wide.
Inflorescence with 4, 6 or 8 flowers; involucre 4.5–6.5 mm long; pedicels 2.5–4 mm long, densely tomentose, with some hairs appressed; hairs white or cream-yellow, extending onto perianth. Perianth 3.7–5.5 mm long, white or cream-white. Pistil 9–17 mm long, deflexed; pollen presenter 0.8–1 mm long.
Fruit narrowly ovate to lanceolate with an obliquely transverse, irregularly-toothed crest c. 1/3 distance from base, 1.6–2.7 cm long, 0.5–0.9 cm wide, finely black-pusticulate or smooth, dark brown-streaked, long-apiculate (often broken); apiculum 6–9 mm long. Seed narrowly elliptic, 11–15 mm long; wing light or dark brown.
Distribution and ecology
Damp areas in mainly coastal heaths from Sydney N.S.W. to Tas. with a disjunct occurrence in the Grampians in western Vic.

Derivation of name
From hirsutus, Latin for hirsute or covered with long, more or less erect hairs, a reference to the hair covering on the pedicels and perianths of this species.
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. teretifolia was treated as as a single member of its own named group, next to the Rostrata group, by Barker et al. (1999). While it lacks the sigmoid fruits of the Rostrata group, the straight fruits that is does possess have characteristics suggesting a relationship to the Rostrata group fruits; H. teretifolia shares the mostly needle leaves, pubescent perianths and oblique pollen presenters of that group.
