Description
Grevillea oleoides is an erect shrub that typically grows to a height of {{cvt|0.5–3|m}} and has angular branchlets. Its leaves are usually egg-shaped with the narrower end towards the base, or narrowly elliptic to more or less linear, {{cvt|50–140|mm}} long and {{cvt|2–20|mm}} wide. The edges of the leaves are turned down or rolled under, the upper surface wrinkled and the lower surface covered with silky to woolly hairs. The flowers are usually arranged on the ends of branches in groups of 12 to 16 on a peduncle up to {{cvt|5|mm}} long, and are red or deep reddish-pink, occasionally pink, the pistil {{cvt|27–36|mm}} long. Flowering mainly occurs from August to November and the fruit is an elliptic follicle {{cvt|10–15|mm}} long.{{cite web |title=Grevillea oleoides |url=https://profiles.ala.org.au/opus/foa/profile/Grevillea%20oleoides |publisher=Australian Biological Resources Study, Department of Agriculture, Water and the Environment: Canberra |access-date=3 August 2022}}
