Grevillea psilantha is an erect shrub that typically grows to a height of up to . Its leaves are linear to narrowly egg-shaped with the narrower end towards the base, long and wide on a short petiole. Both surface of the leaves are similar with several faint, parallel veins.

Grevillea psilantha was first formally described in 1986 by Donald McGillivray in his book New Names in Grevillea (Proteaceae) from specimens collected by Kevin Francis Kenneally, in the Bungle Bungle Range in 1984.[2] The specific epithet (psilantha) means "smooth-flowered".[3]
This grevillea grows in crevices in the walls of sandstone gorges in the Bungle Bungle Range, in the eastern part of Kimberley region of Western Australia.
Grevillea psilantha 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]
