The Gila Brickellbush is known only from the type that was collected in 1903 from alluvial soil at the river bank of the Gila River in Grant County, New Mexico, USA.

The species was never found since and is considered extinct.

***

The species is not accepted by all botanists and is considered by some to be an aberrant individual of the Chihuahuan Brickellbush (Brickellia floribunda A. Gray) (see photo below).
