Description
Spreading or rounded shrub, 1–5(-6) m tall; lignotuberous. Branchlets and young leaves white appressed-pubescent. Leaves terete, 2–15 cm long, 0.8–1.7 mm wide, ascending, not grooved, glaucous.
Inflorescence with 1–10 flowers; involucre 2–3 mm long; rachis knob-like; pedicels 2.5–6.5 mm long, white appressed-pubescent, with hairs extending onto perianth. Flowers bisexual. Perianth 3.5–5.5 mm long. Pistil recurved, 7.8–11.5 mm long; pollen presenter oblique with cone 0.15–0.3 mm high; gland V-shaped, 0.1–0.3 mm high.
Fruit sigmoidal, 2.2–4.5 cm long, 1.8–3.2 cm wide, coarsely wrinkled; beak reflexed, narrow, 7–14 mm long. Seed 13–22 mm long; wing decurrent halfway down one side of seed body only.
Distribution and ecology
Occurs in southern S.A., from Fleurieu Penin. to the South-East, including Kangaroo Is., to the Grampians and Wimmera region in Vic.
Found in a variety of soils in sclerophyllous woodland or forest.

Flowering time
Flowers July–Nov.
Derivation of name
From rostratus, Latin for beaked or curved, a reference to the pronounced recurvature of the beak of the fruit.
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.
The Rostrata group all share the characteristics of pubescent pedicel and perianth, oblique pollen presenter and woody, sigmoid fruits which are retained on the bushes.
Members of the group are H. cyclocarpa, H. epiglottis, H. megadenia , H. rostrata and H. rugosa .
Notes
Usually a rounded shrub of 1-2 m in height and width, H. rostrata does occasionally become almost tree-like and up to 6 m high. This has been particularly observed on Kangaroo Island and may have to do with a differing fire regime or soil type.
Previous Tas. records of this species represent part of the variation of the H. epiglottis complex.
