Grevillea subterlineata is a species of flowering plant in the family Proteaceae and is endemic to a restricted area in the southwest of Western Australia. It is an open shrub with linear leaves and clusters of pink-tinged, white flowers.
Grevillea subterlineata is an open shrub that typically grows to a height of and has silky-hairy branchlets. The leaves are linear, long, wide and have the edges rolled under, with 3 longitudinal veins on the lower surface. The flowers are arranged in down-curved or pendulous, oval to cylindrical clusters on a woolly-hairy rachis long. The flowers are white with a pink tinge, the style with a green tip, and the pistil long. Flowering occurs in August.[1]
Grevillea subterlineata was first formally described in 1993 by Robert Owen Makinson in Grevillea, Proteaceae: a taxonomic revision.[2] The specific epithet (subterlineata) means "marked beneath by fine parallel lines".[3]
This grevillea is only known from an area east of Gascoyne Junction in the Carnarvon, Gascoyne and Murchison bioregions of south-western Western Australia, where it grows in open shrubland and mulga woodland.
Grevillea subterlineata is classified as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, meaning that it is poorly known and known from only a few locations but is not under imminent threat.[4]
