Perhaps no other species of Eucalyptus has proved of so much interest to botanists as has Eucalyptus orbifolia. In 1865, Charles Harper, while exploring country to the east in search of land suitable for grazing, collected at the foot of granite rocks in latitude 30° 47' and longitude 119° 25' a small fragment of Eucalyptus consisting of two or three leaves, one flower bud and one expanded blossom. There were no fruits collected. This fragment was described by the Government Botanist of Victoria, Baron Sir Ferdinand Mueller, under the above name, and the specimen was sent to the Royal Botanic Gardens, Kew, where it exists today. The original locality is close to Tin Hill on the track leading from Southern Cross to the Koolyanobbing Range, but it remained undiscovered, despite searches for it until May, 1940, when Mr. G. E. Brockway found it at Hospital and Pigeon Rocks to the west of Mulline and northwards from Bullfinch respectively. Still more recently it has been found 14 miles north-easterly from Weira Siding.
