Grevillea halmaturina is a species of flowering plant in the family Proteaceae and is endemic to South Australia. It is a prickly, spreading to erect shrub with sharply-pointed, linear to more or less-cylindrical leaves and large groups of white to pale pink flowers.
Grevillea halmaturina is a prickly, spreading to erect shrub that typically grows to a height of 0.3–1.5 m (1 ft 0 in – 4 ft 11 in) and has ridged branchlets. Its leaves are sharply-pointed linear to more or less cylindrical or tapering, 10–30 mm (0.39–1.18 in) long and 0.8–1.2 mm (0.031–0.047 in) wide with the edges rolled under, enclosing most of the lower surface. The flowers are white to pale pink and are arranged in large, sessile groups on the ends of branches or in leaf axils, the pistil 6–8.5 mm (0.24–0.33 in) long. Flowering occurs from July to November and the fruit is a smooth, narrowly oval follicle 10–14 mm (0.39–0.55 in) long.[2]
Grevillea hakeoides was first formally described in 1890 by Ralph Tate in his book A Handbook of the Flora of Extratropical South Australia.[3][4] The specific epithet (halmaturina) is derived from Halmaturus, a name once applied to a genus of kangaroos, and commonly used for species from Kangaroo Island.[5]
In 2000, Robert Owen Makinson described two subspecies of G. halmaturina in the Flora of Australia and the names are accepted by the Australian Plant Census:
Both subspecies mostly grow in shrubby woodland, often in moister places. Subspecies halmaturina is endemic to Kangaroo Island and subspecies laevis is endemic to the southern part of the Eyre Peninsula.[7][9]
