It is only found near Dalwallinu growing amongst medium  or low trees in sandy soils. Only a single population of the plant is known that is found in a patch of remnant vegetation on degraded road reserve. "Grevillea pythara" was discovered by, Jan Wellburn, the daughter of a nearby landowner. It was declared rare in 1994 and critically endangered in 1995.
