T: South Coast, Bay X, [Port Lincoln, S.A.], Mar. 1802, R.Brown Iter Austral. 2; syn: AD, BM, DBN, E, G, K, MEL.


Dense divaricate hermaphrodite shrub, 0.7–2 m tall. Branchlets and young leaves white appressed-pubescent. Leaves rigid, terete, 1.5–6 cm long, 0.9–1.3 mm wide, not grooved, glaucous.

Inflorescence with 6–10 flowers; involucre 3.5–4.5 mm long; rachis knob-like; pedicels 2–3.5 mm long, appressed-pubescent, with hairs white or ferruginous; white hairs extending onto perianth. Flowers bisexual. Perianth 3–3.5 mm long. Pistil erect, 4.5–6 mm long; pollen presenter conical, 0.3–0.4 mm high; gland V-shaped, 0.2–0.4 mm high.

Fruit sigmoidal, 1.5–2.2 cm long, 0.7–1.6 cm wide, coarsely rugose; apiculum 3–7 mm long. Seed 9.5–15 mm long; wing ±apical only.

Distribution and ecology

Occurs from Eyre Penin. in S.A. to western Vic., in mallee scrub or coastal heath, usually on sand or loam.

Flowering time

Flowers Aug.–Oct.

Derivation of name

From rugosus, Latin for somewhat wrinkled, presumed to be a reference to the fruit surface.



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.

The Rostrata group all share the characteristics of pubescent pedicel and perianth, oblique pollen presenter and woody, sigmoid fruits which are retained on the bushes.

Members of the group are H. cyclocarpa, H. epiglottis, H. megadenia , H. rostrata and H. rugosa.


Specimens from the western end of Kangaroo Is. need to be investigated further as they tend to have larger fruit (2.5–2.8 cm long), and the leaves are not always short and straight as in typical H. rugosa. The most marked specimen of this (J.B.Cleland, Snake Lagoon, AD) does not have any flowers.

A collection by Mueller from rocky declivities towards the source of the Macallister R., Vic., also appears to represent this species.
