Maiden & Blakely, Crit. Revis. Eucalyptus 8: 41 (1929).
- TYPE: Western Australia,Watheroo rabbit fence, c. 60 miles E. of Watheroo, M. Koch 1608, 9.1905 (lecto NSW, fide J & H).
- Eucalyptus oleosa var. kochii C. Gardner,
J. & Proc. Roy. Soc. Western Australia 34: 78 (1950).
- TYPE: Western Australia, Rabbit-proof fence, 25 m. E. from Dalwallinu, C.A. Gardner 8524 (holo PERTH). Although Gardner based his variety on E. kochii Maiden & Blakely and used their epithet, he published it as a "var. nov." and cited a different type. The author citation is hence as above, and does not acknowledge Maiden & Blakely. Gardner also included Koch collections probably representing part of Maiden & Blakely's type material in his specimen citation.
