Description

Bushy dense low shrub, 1–2 m tall, lignotuberous. Branchlets densely shiny appressed-pubescent. Leaves simple, 3.2–11.5 cm long, 0.8–1.5 mm wide, ±glabrous; mucro 0.7–1 mm long.

Inflorescence erect, often arising from old wood, with 4–10 flowers; rachis 4–30 mm long, sparsely to densely pubescent; pedicels 4–11 mm long. Perianth 10.5–12 mm long, pink to crimson. Pistil 40–45 mm long; pollen presenter a lateral disc.

Fruit obliquely ovate, sometimes broadly so, 4.5–7 cm long, 3.3–4.5 cm wide, roughly and deeply wrinkled, whitish-pusticulate; beak smooth, tuberculate; apiculum obscure or to 1 mm long; horns to 4 mm long, often obscure. Seed 38–55 mm long; wing encircling seed body asymmetrically.

Distribution and ecology

Restricted to the near coastal area between Newcastle and Hawkesbury R., N.S.W. Occurs in dry sclerophyll forest or windswept heath.

Relationships

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.

Within this section 5 species were assigned to the informal Verrucosa group by Barker et al. (1999). This group is not monophyletic but is held together by the shared morphological characteristics associated with bird pollination. All species have large pink or red flowers in which the tepals remain fused, splitting to the base only between the upper pair and they have a long pistil usually with a lateral pollen presenter.

 

Members of the group are H. bakeriana, H. pendens, H. purpurea, H. rhombales and H. verrucosa. While two of the species are found in SW WA and two are found in eastern Australia one of them (H. rhombales ) is found in central Australia.
