Grevillea arenaria , commonly known as sand grevillea [3] or hoary grevillea, [4] is a species of flowering plant in the family Proteaceae and is endemic to New South Wales. It is a spreading shrub with elliptic to egg-shaped leaves with the narrower end towards the base, and red, pink or orange flowers.
Grevillea arenaria is an erect to spreading shrub that grows to a height of 0.3–4 m (1 ft 0 in – 13 ft 1 in). The leaves are elliptic to egg-shaped with the narrower end towards the base, 15–75 mm (0.59–2.95 in) long and 3–15 mm (0.12–0.59 in) wide with the edges turned down or rolled under. The flowers are arranged in groups of two to six on the ends of short side branches along a rachis 1–10 mm (0.039–0.394 in) long, and are red, pink or orange and hairy. The pistil is 24–32 mm (0.94–1.26 in) long and the ovary is sessile. Flowers are present in most months with a peak in spring. [5] [6]
Grevillea arenaria was first formally described in 1810 by Robert Brown in Transactions of the Linnean Society of London from specimens collected near Port Jackson. [7] [8]
The names of two subspecies are accepted by the Australian Plant Census:
This grevillea grows in open forest, often in rocky places, near creeks or cliffs in south-eastern New South Wales. Subspecies arenaria mostly occurs on the eastern side of the Great Dividing Range and nearby ranges from Richmond to the Deua River and subspecies canescens is mostly found on the drier, western side of the ranges, from Tamworth and Gilgandra to Bathurst and western parts of the Blue Mountains. [5] [10] [12]
Grevillea arenaria is listed as "Least Concern" on the IUCN Red List of Threatened Species. It is widely distributed and its population is presumed stable, or in minor decline. There are currently some localised threats to this species, but none that would significantly affect its population. [1]
Grevillea buxifolia, commonly known as grey spider flower, is a species of flowering plant in the family Proteaceae, and is endemic to New South Wales, Australia. It is an erect to spreading shrub with elliptic to egg-shaped leaves, and woolly-hairy clusters of rust-coloured to fawn flowers.
Grevillea rosmarinifolia, commonly known as rosemary grevillea, is a species of flowering plant in the family Proteaceae and is endemic to south-eastern continental Australia and naturalised in other parts of the country. It is usually an erect, compact to open shrub with linear, narrowly elliptic or narrowly oblong leaves with the edges rolled under, and loose clusters of pink to red flowers.
Grevillea juniperina, commonly known as juniper- or juniper-leaf grevillea or prickly spider-flower, is a plant of the family Proteaceae native to eastern New South Wales and southeastern Queensland in Australia. Scottish botanist Robert Brown described the species in 1810, and seven subspecies are recognised. One subspecies, G. j. juniperina, is restricted to Western Sydney and environs and is threatened by loss of habitat and housing development.
