EUCALYPTUS CAMALDULENSIS

First up was the tree's Aboriginal history. The Kaurna people, original inhabitants of the Adelaide Plains, called it Karra or more fully, Karrawirraparri (literally 'redgum-forest-river'). The tree was central to their lives as source of food and shelter, and supplier of timber for shields and other implements. 
Ironically the tree's botanical name, Eucalyptus camaldulensis, originated in 1832, when a botanist admired and named a single specimen grown by monks outside Naples. The eucalyptus was already spreading in 1832.

Frederick Dehnhardt was chief gardener of L' Hortus Camalduensis di Napoli, also known as the Camaldoli gardens, a private garden owned by the Count of Camaldoli, near Naples, Italy. Here, Dehnardt grew, and named, the type specimen of the River Red Gum, Eucalyptus camalduensis in 1832. His botanical specimens are housed in the Natural History Museum, Vienna, Austria.
