Description

Multistemmed shrub or tree to 7 m high, lignotuberous. Branchlets and young leaves densely ferruginous appressed-pubescent. Leaves narrowly elliptic, 7.5–28.5 cm long, 0.6–3 cm wide, narrowly attenuate, long acuminate, with mucro 1–3 mm long; longitudinal veins pinnate, distally 3 or 5, with secondary veins between rarely obviously anastomosing; petiole 1–1.5 cm.

Inflorescence with 70–110 or more flowers; rachis 4–7.5 cm long, densely, rarely moderately, appressed-pubescent; pedicels 1.2–2 mm, glabrous, reddening. Perianth 7–10 mm long, green, glabrous or with scattered hairs in bud. Pistil 23–27 mm long; style red.

Fruit valves obliquely ovate, 1.5–2.2 cm long, 1.2–1.4 cm wide; red-brown wood zone 1–1.5 mm wide. Seed narrowly obovate, 14–20 mm long.

Distribution and ecology

Restricted to uplands between Taree and Wauchope, north-eastern N.S.W. Occurs in a composite of wet sclerophyll forest and rainforest on hill slopes, on Triassic conglomerate.

Flowering time

Flowers Oct. to Dec.

Relationships

Referred to the Trineura Group of Barker et al. (1999), these 2 species (H. trineura and H. archaeoides) have been assumed to be, along with the corkwoods, part of the basal group of Hakea. Both occur in north-eastern regions of Australia.

Bentham referred H. trineura to the Grevilleoides, because it shares the long floriferous inflorescences of the corkwood group, and has oblique pollen presenters, but the flat leaves of these two species have a very obvious venation and the fruits are woody.

Notes

Allied to H. trineura , and formerly confused with it. The two species are similar in their flat leaves with prominent longitudinal veins above and along margins, their long racemes, oblique pollen presenters, and fruit lacking horns, but H. archaeoides differs from H. trineura by its secondary venation not obviously anastomosing, by its more densely pubescent rachis, by its green tepals and red style, and by its smaller fruit and seed.

Conservation status

See the current list of Hakea species gazetted in the Threatened Flora of  the Australian Government's Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).

Hakea archaeoides: approved conservation advice (approved Oct. 2008).

A profile of Hakea archaeoides, otherwise known as Big Nellie Hakea, as a vulnerable species, can be found on the Threatened Species site of the NSW Department of Environment & Conservation.
