Description

Low erect shrub to 1.5 (–2) m high, lignotuberous. Leaves oblanceolate to narrowly oblanceolate, 6–13 cm long, (8–) 14–30 mm wide, usually obtuse, more rarely acute or acuminate, blackened apically but scarcely mucronate, moderately appressed-sericeous with white and ferruginous hairs when young, rapidly glabrescent. Involucral buds 1.5 mm long, externally pubescent.

Inflorescence 1–4 umbels of 14–20 white flowers per axil, often arising on old rachises in lower axils; rachis 3–4 mm long; pedicels 4–7.5 mm long. Perianth 3.5–4 mm long. Pistil 7–10 mm long.

Fruit obliquely elliptic, 2–2.6 cm long, 0.6–1.2 cm wide in median view, black-pusticulate; pusticules raised but rarely tuberculate, and if so, only to 1 mm high; beak pusticulate; red-brown wood zone 0.5–0.7 mm wide at widest point. Seed 16–18 mm long.

Distribution and ecology

Occurs in coastal areas of south-eastern Qld and northern N.S.W., from Bundaberg south to Grafton; grows in open forest, often associated with Melaleuca, on sand or sandstone, sometimes in poorly drained flats.

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. florulenta was treated as part of the Salicifolia group, an eastern states group characterised by their simple flat leaves, few-flowered inflorescences, glabrous pedicel and perianth and erect fruits, these markedly verrucose or pusticulate and usually with horns.

The only members of this group are H. florulenta and H. salicifolia.
