Grevillea acanthifolia A.Cunn. APNI* Description: Spreading to erect shrub 1–3 m high.
Leaves pinnatifid to pinnatisect, 4–9 cm long, 3–7 cm wide, with 6–14 primary lobes, divaricate (except in subsp. acanthifolia); lobes entire to pinnatisect, (often 3-lobed in subsp. acanthifolia); secondary lobes entire or sometimes 2-lobed (subsp. paludosa); ultimate lobes triangular to linear, 0.5–2 cm long, pungent; margins recurved to revolute, lower surface glabrous to silky.
Inflorescences erect, secund, 3–10 cm long. Perianth pale green to grey, subsericeous to subvillous outside, glabrous inside. Gynoecium 20–28 mm long; ovary densely hairy; style pink to maroon, glabrous, pollen presenter erect to oblique.
Follicle hairy with reddish brown stripes or blotches.
Flowering: mainly October–February
Distribution and occurrence:
NSW subdivisions: NC, NT, CT, ST
Hybridizes with G. laurifolia to produce natural hybrids known as G. X gaudichaudii, where the ranges overlap (e.g. Wentworth Falls to Hartley Vale).
Text by R. O. Makinson Taxon concept:
| Key to the subspecies | |
1 | Leaves with ultimate lobes cuneate or ovate, rarely linear; most of lower surface of lobes exposed, margins recurved; inflorescences usually >5 cm long. Shrub to 2 m high | subsp. acanthifolia |
| Leaves with ultimate lobes linear or subulate; most of lower surface enclosed by the refracted margin; inflorescences usually ≤ 5 cm long | 2 |
2 | Pollen presenter oblique, broad-conical; lower surface of leaves glabrous except for scattered appressed hairs on the veins; branchlets glabrous or pubescent; stipe ≥ 1.5 mm long; low spreading shrub usually <1 m high | subsp. stenomera |
| Pollen presenter an erect cone; lower surface of some or all leaves with white appressed hairs on the lamina on either side of the veins; branchlets subsericeous with ridges sometimes glabrous; stipe ≤ 1.5 mm long; erect spreading shrub up to 3 m high Back to 1 | subsp. paludosa |
