Description

Erect shrub or small tree, frequently with finally pendulous branches, 3–6 m tall, non-sprouting. Branchlets glabrous by flowering. Leaves narrowly obovate-elliptic, 7–21 cm long (including petiole 1–2 cm long), 6–29 mm wide, narrowly attenuate at base, bluntly acute, olive-green, quickly glabrescent; longitudinal veins 3–7; secondary veins sometimes visible.

Inflorescence axillary with 120–190 flowers; pedicels 5.5–9.5 mm long, glabrous. Perianth deep pinkish red. Pistil 14–19.5 mm long, cream-white, rarely deep pink-red; gland a V-shaped flap, 0.6–1.2 mm high.

Fruit 1–10 per axil, ±obliquely ovate-elliptic, 2.2–3.8 cm long, 1.6–2.2 cm wide, sometimes curved at base, shortly beaked, flanged adaxially. Seed ovate, 15–24 mm long; wing extending broadly down both sides of body and narrowly around base, blackish brown to black.

Distribution and ecology

Occurs in south-western W.A. from Wagin south to Denmark and east to Israelite Bay. Naturalised at least in S.A., in the Mount Lofty Ra. and on Kangaroo Is. Grows in mallee-heath in sandy to gravelly, sometimes clay, granitic or lateritic soil.

Flowering time

Flowers Apr.–Aug.

Derivation of name

From laurinus, Latin for "of laurel", and presumably a reference to the resemblance of this species (or its leaves) to the laurel tree.

Relationships

Part of Sect. Conogynoides recognised by Bentham (1870) and characterised by a conical pollen presenter, veined leaves, glabrous perianth and fruits without horns.

 

Within this section 3 species were assigned to the informal Petiolaris group by Barker et al. (1999). This group of Hakea species was combined morphologically because they all have flat, subpetiolate leaves, unusual spherical or sub-spherical inflorescences, long pistils and down-curved fruits.

 

Species are H. laurina, H. obtusa and H. petiolaris, all from SW WA. The monophyly or otherwise of the group has still to be tested.

Notes

Well known in cultivation and probably the most widely grown species of Hakea. Prized for the 'pincushion' inflorescence of cream pin-like styles emerging from a contrasting deep pinkish red 'cushion' of perianths; colour variants occur.
