Trans. Linn. Soc. London 10: 179 (1810) APNI
Slender to rounded shrub, to 2(–4) m high; branchlets ribbed, soon glabrescent. Leaves flexible, not widely spreading, terete to flattened, 0.8–5 cm long, 0.7–2.5 mm wide, glabrous, sometimes grooved below; apex straight. Inflorescence 2–11-flowered; rachis 0.5–1.0 mm long, densely pubescent; pedicels 1.5–3.3 mm long, pubescent; perianth 1.3–2.2 mm long, cream to deep yellow, glabrous; pistil 3–4.5 mm long; pollen presenter an oblique disc. Fruit broad-ovoid to globular, densely warted or almost smooth with age, 1.3–3.5 cm long, 0.9–3 cm wide; hardly beaked; horns absent; seed not occupying whole valve face, obliquely elliptic, 12–23 mm long, 5.5–11 mm wide; wing broadly decurrent down three-quarters or all of one side, rarely narrowly down the other, dark grey to grey-yellow.

Remarkable for producing 2 fruit types, one with a smooth surface, not developing any marked woodiness and opening while still attached to the bush, the other woody and usually with a rough tuberculate surface, which remains closed while attached to the bush. Woody fruits in Victoria are usually less than 2.5 cm long and 1–1.5 cm wide. The smooth-surfaced fruit was the basis for Hakea flexilis, described at the same time as H. nodosa.
