Distribution and growth form

Eremophila biserrata is endemic to the Coolgardie woodlands ecoregion of southwest Australia. Its characteristic growth form is in large expanses of low low lying mats. This prostrate growth form is the origin of an alternative common name for the species of Prostrate Eremophila.

An important E. biserrata vegetative association is found in the southwestern part of the Coolgardie region where open mats of Eremophila biserrata are seen under melaleuca scrub and open tree mallee; this assemblage is one of the bleakest barren looking plant assemblies of the ecoregion, and is evidenced for example somewhat to the north of Lake Cronin.
