Grevillea acanthifolia, commonly known as the Acanthus-leaved grevillea, is a plant in the family Proteaceae and is endemic to New South Wales. It is a shrub with stiff, prickly, divided leaves and pink to purple "toothbrush" flowers.
Grevillea acanthifolia is an erect or spreading shrub which usually grows to a height of 0.5 m (2 ft) but sometimes to 3 m (10 ft) tall and 4 m (10 ft) wide. The leaves have 9 to 14 main lobes and are 4–9 cm (2–4 in) long and 3–7 cm (1–3 in) wide, each lobe sometimes further divided and linear to triangular or wedge-shaped with a sharp tip. The leaves are bright green, stiff and prickly.[2][3][4][5]
The flowers are arranged in one-sided, "toothbrush"-like group, 3–10 cm (1–4 in) long. The small sepals and petals are pale green to grey and hairy on the outside and glabrous inside. The style is 20–28 mm (0.8–1 in) long and red, tipped with a green pollen presenter. Flowering occurs throughout the year but mainly from October to February and the fruit that follows is a hairy follicle with reddish markings.[2][3][4][5]
Grevillea acanthifolia was first formally described in 1825 by Allan Cunningham from a specimen he collected on John Oxley's 1817 expedition. Cunningham found the species growing in "peaty bogs on the Blue Mountains and [on the] banks of Cox's River".[6] The specific epithet (acanthifolia) is a derived from the name of the genus Acanthus and the Latin word folium meaning "a leaf"[7] referring to the similarity of the leaves of this species to those of Acanthus.[3]
The names of three subspecies are accepted by the Australian Plant Census:
Grevillea × gaudichaudii is a hybrid derived from G. acanthifolia and Grevillea laurifolia.
This grevillea only grows in New South Wales, usually at higher altitudes and in wet or boggy areas.[2]
Subspecies stenomera is classified in the ROTAP system as 3RC-[13] meaning that it has a wide range but small populations and is rare, but at least some populations are in reserves and the species not at present under threat.[14] Subspecies paludosa is classified as "Endangered" under the NSW Threatened Species Conservation Act and under the Commonwealth Government Environment Protection and Biodiversity Conservation Act 1999 (EPBC) Act. The main threats to its survival are habitat loss, changes to river flow regimes and trampling and grazing by stray domestic animals.[15][16]
Subspecies acanthifolia of this grevillea is grown in some gardens but is sometimes unreliable at low altitudes. It grows best in a sunny position and is tolerant of heavy frosts.[3]

Grevillea acanthifolia es un arbusto endémico de Nueva Gales del Sur en Australia.
Alcanza los 3 metros de altura y tiene las hojas divididas. Las flores tienen perianto de color verde a gris con carpelos de color rosa a marrón. Florecen a mediados de verano.
La especie fue descubierta por el botánico Allan Cunningham que acompañaba a J.Oxley en su expedición de 1817. Cunningham encontró la especie en las Montañas Azules. La especie fue descrita formalmente en 1825 y publicado en Geogr. Mem. N. S. Wales 328 en el año 1825.
Tiene tres subespecies:
Grevillea, el nombre del género fue nombrado en honor de Charles Francis Greville, co-foundador de la Royal Horticultural Society.
acanthifolia, epíteto que hace referencia a la similutud de su follaje con el del género Acanthus.[1]
Grevillea acanthifolia es un arbusto endémico de Nueva Gales del Sur en Australia.
Grevillea acanthifolia est un arbuste qui est endémique de la Nouvelle-Galles du Sud en Australie.
Il peut mesurer jusqu'à 3 mètres de hauteur et a les feuilles divisées. Les fleurs disposées en « brosse à dents » ont un périanthe allant du vert au gris avec un style rose à marron et un stigmate vert. Elles apparaissent du milieu du printemps à la fin de l'été (d'octobre à février en Australie).
Le spécimen-type a été recueilli par le botaniste Allan Cunningham qui a accompagné John Oxley lors de son expédition de 1817. Cunningham a constaté que l'espèce croissait dans "les marais tourbeux des Blue Mountains et sur les bords de la Cox's River». Il a décrit l'espèce en 1825.
