Grevillea hislopii is a dense, single-stemmed shrub that typically grows to up to high and wide. Its adult leaves are linear to narrowly elliptic, long and wide on a petiole up to long and with a small point up to long on the tip. The lower surface of the leaves is densely hairy. The flowers are arranged in leaf axils or on the ends of branchlets in clusters on a rachis long, each flower on a pedicel long. The flowers are greyish-white, hairy and slightly rust-coloured, the style white and slightly pink with a green tip, the pistil long.

Grevillea hislopii was first formally described in 2008 by Peter M. Olde and Neil R. Marriott in the journal Nuytsia from specimens they collected near Perth in 2002.[2] The specific epithet (hislopii) honours Michael Clyde Hislop.[3]
This grevillea grows in open woodland near creeks and drainage lines in a small area west of York in the Jarrah Forest bioregion of south-western Western Australia.
Grevillea hislopii is listed as "Priority Two" by the Western Australian Government Department of Biodiversity, Conservation and Attractions, meaning that it is poorly known and from only one or a few locations.[4]
