Description

Erect rounded or sprawling shrub, 1–4.5 m tall, non-sprouting. Branchlets densely tomentose with colourless hairs at flowering. Leaves narrowly to broadly ovate or elliptic, ±flat, 1.5–8.5 cm long, 12–27 mm wide, cordate to broadly cuneate at base, crenate to ±entire, acute, pale green; longitudinal or palmate veins 3, rarely 5; secondary veins reticulate, prominent.

Inflorescence solitary with 16–20 flowers; pedicels glabrous. Perianth cream-white. Pistil 6.5–10.5 mm long; gland present.

Fruit obliquely ovate, 2–3.1 cm long, 1.1–1.8 cm wide, sometimes with recurved apex, beaked. Seed narrowly ovate or elliptic, 14–18 mm long; wing extending narrowly and fully or partly down one side of body only, blackish brown throughout.

Distribution and ecology

Occurs in the southern coastal region of south-western W.A., from Albany to Esperance and inland to the Stirling Ra. Found in mallee-heath or open forest, usually in lateritic sand.

Flowering time

Flowers July–Nov.

Derivation of name

From ferrugineus, Latin for rusty, a reference to the colour of the new growth.

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

H. ferruginea is very close to H. hastata (q.v.).

[Paust collections indicate flowers are green and red.

Fruits on collections usually only splitting slightly, not opening widely to expose seeds as in most Hakeas. Is this significant as in for example H. neurophylla ?]rmb
