 Plants similar to the type specimen, commonly referred to as the "T-form", were first collected in 1792 by the French exploration of Australia's southern coast led by Bruni d'Entrecasteaux.The naturalist on board that expedition, Jacques Labillardière, first described "D. binata" in his 1804 publication on the flora of Australia, "Novae Hollandiae Plantarum Specimen".The T-form, so named for its single leaf bifurcation spreading into a T-shape, is a robust plant from temperate zones that can grow up to and has green foliage that becomes redder with age.
