Description
Grevillea patulifolia is an erect or low, spreading shrub that typically grows to a height of {{cvt|0.2–2|m}} and that sometimes forms root suckers. Its leaves are more or less linear to narrowly elliptic, {{cvt|15–35|mm}} long, {{cvt|1.0–1.5|mm}} wide and sharply pointed. The edges of the leaves are rolled under, often obscuring most of the lower surface. The flowers are arranged at the ends of branches in clusters of many flowers, the clusters usually shorter than the leaves. The flowers are pale pink to dark mauve-pink, the style sharply curved near the tip and the pistil {{cvt|8.0–8.5|mm}} long. Flowering occurs from July to February and the fruit is a narrowly elliptic follicle about {{cvt|11|mm}} long.{{cite web |title=Grevillea patulifolia |url=https://profiles.ala.org.au/opus/foa/profile/Grevillea%20patulifolia |publisher=Australian Biological Resources Study, Department of Agriculture, Water and the Environment: Canberra |access-date=10 August 2022}}{{cite web |last1=Makinson |first1=Robert O. |last2=Stajsic |first2=Val |title=Grevillea patulifolia |url=https://vicflora.rbg.vic.gov.au/flora/taxon/6135b427-34d0-4b60-b7a5-6db615ac8e97 |publisher=Royal Botanic Gardens Victoria |access-date=10 August 2022}}{{cite web |last1=Makinson |first1=Robert O. |title=Grevillea patulifolia |url=https://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Grevillea~patulifolia |publisher=Royal Botanic Garden Sydney |access-date=10 August 2022}}
