The specific epithet, henrylawsoni, is in honor of the Australian author, poet, and philosopher Henry Lawson.

P. henrylawsoni is similar to the larger central bearded dragon (P. vitticeps), but is usually less than 30 cm (12 in) in total length (including tail), with a shorter and more blunt snout.

The scientific name for this species was disputed, along with the other taxonomic treatments of Wells and Wellington,[4] but was published again by Harold Cogger (2000) and others as a valid name.

[8] The Rankins dragon requires a minimum of 40 gallons and a hide, as well as multiple places to climb.

The only issue is the small gene pool within captive populations, being unable to be supplemented by wild individuals from Australia, whereas deformation of the spine is occurring.
