Description

edit

Grevillea quercifolia is a straggly to sprawling shrub that typically grows to up to 0.6 m (2 ft 0 in) high and 1–3 m (3 ft 3 in – 9 ft 10 in) wide. Its leaves are usually pinnatifid to more or less serrated, glabrous, oblong to narrowly egg-shaped, mostly 35–200 mm (1.4–7.9 in) long and 25–60 mm (0.98–2.36 in) wide, with about 5 to 15 triangular to oblong lobes 5–15 mm (0.20–0.59 in) long and 2–10 mm (0.079–0.394 in) wide. The flowers are usually arranged on the ends of branches in oval to cylindrical clusters on a rachis 15–50 mm (0.59–1.97 in) long, and are pale to deep pink, the pistil 9–11.5 mm (0.35–0.45 in) long. The fruit is an oval to elliptic follicle 18–20 mm (0.71–0.79 in) long.[2][3]

Taxonomy

edit

Grevillea quercifolia was first formally described in 1830 by Robert Brown in his Supplementum primum prodromi florae Novae Hollandiae.[4][5] The specific epithet (quercifolia) means "oak-leaved".[6]

Distribution and habitat

edit

Oak-leaved grevillea is widespread in the south-west of Western Australia, where it grows in heathland, shrubland or woodland from a little north of Perth to Augusta and east to Mount Barker and Albany in the Jarrah Forest, Swan Coastal Plain and Warren bioregions of south-western Western Australia.[2][3]

Conservation status

edit

This grevillea is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.[2]
