About Grevillea arenaria R.Br.
Grevillea arenaria is an erect to spreading shrub that reaches a height between 0.3 and 4 metres (1 foot to 13 feet 1 inch). Its leaves are elliptic to egg-shaped, with the narrow end towards the base, and measure 15 to 75 millimetres (0.59 to 2.95 inches) long by 3 to 15 millimetres (0.12 to 0.59 inches) wide, with edges that are turned down or rolled under. Flowers are arranged in groups of two to six on the ends of short side branches, along a rachis 1 to 10 millimetres (0.039 to 0.394 inches) long. The flowers are red, pink, or orange, and are hairy. The pistil is 24 to 32 millimetres (0.94 to 1.26 inches) long, and the ovary is sessile. Flowers appear in most months of the year, with a peak flowering period in spring. This grevillea grows in open forest, most often in rocky locations near creeks or cliffs, in south-eastern New South Wales. The nominate subspecies, G. arenaria subsp. arenaria, occurs mostly on the eastern side of the Great Dividing Range and nearby adjacent ranges, between Richmond and the Deua River. Subspecies canescens occurs mostly on the drier western side of the ranges, from Tamworth and Gilgandra to Bathurst and the western parts of the Blue Mountains.
