Grevillea prominens is a species of flowering plant in the family Proteaceae and is endemic to a restricted part of the South West region of Western Australia. It is a shrub with divided leaves, the end-lobes linear to narrow triangular, and creamy-white flowers usually projected beyond the foliage.
Grevillea prominens is a shrub that typically grows to a height of and has glabrous branchlets. The leaves are long and divided with three lobes, each usually divided again with a further three lobes, the end lobes linear to narrow triangular, long and wide with the edges rolled under. The flowers are arranged on the ends of branchlets, in usually branched clusters, usually beyod the foliage, more or less on one side of a glabrous rachis long. The flowers are creamy-white, the pistil long. Flowering mainly occurs in September and October and the fruit is an egg-shaped follicle long.[1] [2]
Grevillea prominens was first formally described in 1993 by Peter Olde and Neil Marriott in the journal Nuytsia from specimens collected near Harvey in 1991.[3] The specific epithet (prominens) means "prominent", referring to the flowers held conspiculusly above the foliage.
This grevillea grows in forest along creek lines and is only known from a few locations near Harvey in the Jarrah Forest bioregion of south-western Western Australia.
Grevillea prominens is listed 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]
