Synonymy

Hakea ednieana Tate, Trans. & Proc. Roy. Soc. S. Australia 7: 70 (1885)

T: without locality [stony slopes of the Aroona Ra., bordering the Basin of L. Torrens on the east, S.A.], s.d., Anon. [?R.Tate] 382; holo: n.v., probably lost.

Description

Shrub or small tree 2–5 m high, sometimes multi-stemmed probably indicating ability to sucker. Branchlets white-pubescent, glabrescent. Leaves compound, terete, 2–7 cm long, white-pubescent; final segments 1–14, 0.1–3.6 cm long, 0.7–1.8 mm wide, spreading; apex straight; undivided base 0.6–4 cm long.

Inflorescence with 35–100 flowers; rachis 20–75 mm long, appressed white-pubescent, with indumentum similar on pedicel and perianth. Flowers white; pedicels 3–9 mm long. Perianth slightly bent in mature bud, 2–5 mm long. Pistil 8.5–11 mm long; style ±straight; pollen presenter porrect, conical.

Fruit 20–28 (–34) mm long, often pubescent, glabrescent; valves 7–11 mm wide; red-brown wood zone 0.5–1 mm wide; pale wood zone (2–) 3–4 (–4.5) mm wide; beak very long, wide; horns rarely conspicuous and up to 2 mm long. Seed occupying most of valve, 19–26 mm long, 6–10 mm wide; wing terminal on seed body to decurrent c. 1/3 way down one side only.

Distribution and ecology

Occurs in the Flinders Ra., S.A., with a disjunct occurrence on Floods Creek Stn, north-western N.S.W. Found on rocky cliff faces and in creek lines.

Flowering time

Flowers Sept.–early Dec.

Derivation of name

"I have much pleasure in imposing on it one of the names of the Conservator of Forests, Mr J. Ednie Brown, F.L.S. [1848-1899], whose "Forest Flora of South Australia" claims some complimentary recognition by the systematic botanist."    Quoted from protologue (Tate 1885).

Relationships

Part of the group referred to as the Corkwoods (Grevilleoides p.p. of Bentham, Lorea group of Barker et al. 1999) because the bark of these plants is usually corky. Pollen presenters are usually not conical (except in H. ednieana), leaf venation is obscure, inflorescences are long and floriferous and mostly pendent and many fruits are formed. These fruits are not particularly woody, are usually obscurely horned, not usually retained for a long time on the plant and the seed occupies most of the valve face.

 

Members of this group include H. chordophylla, H. divaricata, H. ednieana, H. eyreana, H. fraseri, H. ivoryi, H. lorea, H. macrocarpa and H. pulvinifera . They tend to occur in drier areas of Australia.

Notes

Distinctive within the section for its buds almost straight just prior to anthesis, shorter perianth and porrect pollen presenter. The N.S.W. population has a slightly more oblique pollen presenter and recurved bud which tend to place it intermediate with H. eyreana .

Representative specimens
