Synonymy

Hakea elliptica (Sm.) R.Br., Trans. Linn. Soc. London 10: 187 (1810)

Conchium ellipticum Sm., in A.Rees, Cycl. 9 (1807), pages unnumbered. T: King George Sound, [W.A.], 1803 [26 Sept.–15 Oct. 1791], A.Menzies s.n.; holo: LINN; iso: BM, ?K p.p.

Description

Erect shrub, 2–4 m tall, non-sprouting. Branchlets densely tomentose with reddish brown hairs at flowering. Leaves elliptic to broadly elliptic, ±flat, 4.5–9.5 cm long, 15–55 mm wide, cuneate to almost rounded at base, finely crenate, obtuse and blunt, short-acuminate or emarginate; longitudinal veins 3–5 above and below; secondary veins reticulate, prominent.

Inflorescence solitary with 35–40 flowers; pedicels glabrous. Perianth cream-white. Pistil 6–7.5 mm long; gland present.

Fruit obliquely elliptic, 3–3.7 cm long, 1.8–2.2 cm wide, not curved apically, not or obscurely beaked. Seed obliquely ovate, 20–25 mm long; wing extending broadly down one side of body, narrowly and partly down other, blackish brown, sometimes with paler patches.

Distribution and ecology

Occurs at a few localities along the south coast of south-western W.A., from Nornalup to just east of Albany, and on nearby offshore islands. Found in association with granite outcrops in heath.

Flowering time

Flowers Dec.

Derivation of name

From ellipticus, Latin for elliptic, presumably a reference to the shape of the leaves.

Relationships

Part of the Conogynoides group recognised by Bentham and characterised by a conical pollen presenter, veined leaves, glabrous perianth and fruits without horns.

 

Within this section 12 species were assigned to the informal Undulata group by Barker et al. (1999). This group of Hakea species was combined morphologically because they all have simple flat leaves with 3-7 prominent longitudinal veins, 10-40 small flowers (with 3-10.5 mm long pistils) and decurved woody fruits.

Members of the group are H. ambigua, H. anadenia, H. dactyloides, H. elliptica, H. falcata, H. ferruginea, H. hastata, H. laevipes, H. loranthifolia , H. neurophylla, H. plurinervia and H. undulata , from the eastern states and from SW WA. The newly described H. oligoneura (Nuytsia 19: 254 (2009) from the SW coast of WA belongs with this group.

Notes

Occasionally grown as an ornamental, when noted for its striking bronze new shoots.
