Abstract
The name Eucalyptus obtusiflora has been applied to both an eastern Australian species and to a distantly-related species from Western Australia. We have re-examined the literature and type material of E. obtusiflora and conclude that the holotype was most likely collected on the west coast of Western Australia, possibly as part of the Baudin Expedition, and was certainly not collected by Sieber, with whom the type specimen has previously been associated.
