Flindersia maculosa is a tree that typically grows to a height of 15 m (49 ft), developing from a tangled mass of spiny branches in the juvenile stage. The trunk is mottled due to the bark shedding in patches.

Flindersia maculosa grows on stony hills and sand plains from Hughenden in central Queensland to the Riverina district in south-western New South Wales and from Walgett to Ivanhoe and Broken Hill in that state.
