Angophora floribunda is a common woodland and forest tree of Eastern Australia and is known by a variety of names including Rough-barked apple, Apple box, Rusty gum, and Boondah.

More recently, genetic work has been published showing Angophora to be more closely related to Eucalyptus than Corymbia

Corymbia

Corymbia is a genus of about 113 species of tree that were classified as Eucalyptus species until the mid-1990s. It includes the bloodwoods, ghost gums and spotted gums. The bloodwoods had been recognised as a distinct group within the large and diverse Eucalyptus genus since 1867...

, and the name Eucalyptus florida has been proposed for this species if it were to be placed in the eucalypt genus.

A. floribunda is a large, wide, spreading tree growing to a height of between 15 and 25 m. The trunk is often gnarled and crooked with fibrous grey bark.
