Grevillea tetragonoloba is a species from southern Western Australia from between Albany and Esperance, where it grows on sandy or loam soils. The genus name Grevillea honors after Charles Francis Greville (1749-1809), a patron of botany, a very close friend of Sir Joseph Banks, and president of the Royal Society of London. The specific epithet is from the Greek words 'tetra' meaning "four" and 'gonia' meaning "an angle" combined with the Latin word 'lobus' meaning "a lobe" in reference to the cross-sectional shape of the leaf lobes.

Grevillea tetragonoloba 'Ray's Red' is a 2016 University of California Santa Cruz Arboretum Koala Blooms Australian Plant Introduction. It was originally received by the arboretum in 1977 as Grevillea tetragonoloba 77.73 and its name honors the late natural history professor Ray Collett (1933-2012), who was the founding director of UCSC Arboretum. This form is possibly the same as what was once sold in Australia incorrectly as fine leafed form of G.hookeriana, a species thought to be one of the parents of Grevillea 'Red Hooks'
