Hakea lasiantha R.Br., Suppl. Prodr. Fl. Nov. Holl. 29 (1830)

T: interior of King George Sound, [Western Australia], 1828/9, W.Baxter s.n.; syn: BM, K, NY.

An image of the NY type specimen can be seen on the New York Botanical Garden site.


Erect branched shrub, 0.6–3 m tall, non-lignotuberous. Branchlets and young leaves woolly-tomentose, ferruginous. Leaves flat, elliptic or obovate, sometimes narrowly so, 2.8–6.3 cm long, 7–17 mm wide, attenuate or rounded, entire, rounded apically.

Inflorescence with 3–8 flowers; involucre 5 mm long; pedicels 4–8 mm long, ferruginous woolly-tomentose. Perianth 5.5–9 mm long, cream-white or yellow-brown woolly-tomentose. Pistil 7.5–9.5 mm long; pollen presenter 1–1.4 mm long; gland 0.2 mm high.

Fruit leaf-like, obliquely narrowly elliptic, 2.6–3.2 cm long, 1–1.1 cm wide, smooth, not beaked. Seed obliquely narrowly obovate, 20–23 mm long; wing partly down only one side of seed body, or apical only.

Distribution and ecology

Occurs in area bounded by Gordon R., the Stirling Ra., Cape Riche and Albany in Western Australia, in mallee scrub on sand, sandy gravel or sandy clay.

Flowering time

Flowers Mar.–Sept.

Derivation of name

From lasios, Greek for hairy or woolly, and anthos, Greek for flower, a reference to the flowers noticeably covered with white woolly hairs in 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.

The Trifurcata group all share the characteristics of compound-terete leaves, pubescent pedicel and perianth, lateral pollen presenter and non-woody, non-horned, camouflaged fruits which are not retained for any length of time on the bushes.

Members of the group are H. erinacea, H. lasiantha, H. lasianthoides, H. longiflora and H. trifurcata , all from SW WA. The monophyly or otherwise of the group has still to be tested.


Specimens with cream-white hairs on the perianth from the Stirling Ra. (and one specimen from Albany) are not separable in any other way from the more typical specimens with yellow-brown hairs from more southerly regions.

Very closely related to H. lasianthoides, but differing from it by the pedicels and perianth with differently coloured hairs (same colour in H. lasianthoides ), the usually wider leaves, the raised hairs in the young parts and in distribution and flowering time.

There are some specimens from Bullsbrook and Collie area which erode the differences between H. lasiantha and H. lasianthoides , particularly by having ferruginous hairs on the pedicel and perianth.  These specimens have been referred to as Hakea sp. walyunga in some literature (Young 2006) and in FloraBase as Hakea sp. Walyunga (Penn s.n.)
