Description

Shrub or small tree 1–8 m high, resprouting from base. Branchlets ferruginous appressed-pubescent to ±woolly-ferruginous over white-tomentose. Leaves terete, not grooved, 3–8 cm long, 1–1.5 (–1.8) mm wide, wholly glabrescent; apex strongly uncinate, with mucro 0.8–2 mm long.

Inflorescence of 6–22 flowers; rachis simple, 1–3 mm long, densely ferruginous appressed-pubescent; pedicels 3.5–7 mm long; pedicel and perianth white and ferruginous appressed-pubescent. Perianth 5–6 mm long. Pistil 7–10 mm long.

Fruit 2–3 cm long, 1.5–2 cm wide, smooth, sometimes pusticulate; horns blunt, usually conspicuous, to 2 mm long. Seed 14–20 mm long, 7–8.5 mm wide; wing decurrent c. 1/2–2/3 way down one side only, grey-yellow to blackish.

Distribution and ecology

Occurs in drier areas of S.A., Qld, N.S.W. and Vic., in open spinifex and blue-bush shrubland.

Flowering time

Flowers Sept.–Oct.

Derivation of name

From tephro-, Greek for ash-grey or grey and spermus, Greek for -seeded, a reference to the colour of the seed of this species.

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.

H. tephrosperma was treated as part of the Sericea group, a predominantly eastern states group characterised by their simple terete leaves, few-flowered inflorescences, hairy pedicels and solitary, prominently woody fruits, these often markedly verrucose or pusticulate and usually with horns.

Other members of the group are H. actites, H. constablei, H. decurrens, H. gibbosa, H. kippistiana, H. leucoptera, H. lissosperma, H. macraeana, H. macrorrhyncha, H. ochroptera and H. sericea, predominantly from the eastern states of Australia.  

Notes

Hakea leucoptera and H. tephrosperma are often confused. Initially they can often be distinguished by the mucro, curved in H. tephrosperma and usually porrect in H. leucoptera. Hakea tephrosperma also has a shorter floral rachis with rust-coloured hairs, and the pedicel and perianth are densely appressed-pubescent with rust and white hairs, while H. leucoptera has a longer floral rachis, often persistent after the flowers have fallen, and the pedicel and perianth are often glabrous. Pubescent flowers in H. leucoptera seem to be confined to S.A. and N.T., and even there in mature flowers it is often only the pedicel and limb of the perianth which have sparse or moderately dense raised white hairs; buds are covered all over with hairs.

A specimen from Dubbo District (J.L.Boorman, BRI 1259538, NSW) has glabrous pedicels and perianth, but matches H. tephrosperma in slender short uncinate leaves, short ferruginous haired rachis, and fruit.
