It is a dense, erect to spreading shrub, usually with pinnatipartite to almost pinnatisect leaves, the end lobes linear, and clusters of yellowish-brown to fawn flowers with a scarlet to orange-red style.
Grevillea tetragonoloba is dense, erect to spreading shrub that typically grows to a height of . Its leaves are long and mostly pinnatipartite to almost pinnatisect with 3 to 13 lobes, the end lobes linear, long, wide, sharply pointed and rectangular in cross-section. The flowers are arranged on one side of a rachis long, the flowers yellowish-brown to fawn with a scarlet to orange-red style, the pistil long.

Grevillea tetragonoloba was first formally described in 1856 by Carl Meissner in de Candolle's Prodromus Systematis Naturalis Regni Vegetabilis from specimens collected by James Drummond in the Swan River Colony.[4] [5] The specific epithet (tetragonoloba) means "four-angled lobe", referring to the cross-sectional shape of the leaf lobes.[6]
This grevillea grows in mallee heath, woodland and shrubland between Cape Riche and Needilup and near Bremer Bay in the Esperance Plains, Jarrah Forest and Mallee bioregions of south-western Western Australia.
Grevillea tetragonoloba is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
