TYPE: Western Australia,Watheroo rabbit fence, c. 60 miles E. of Watheroo, M. Koch 1608, 9.1905 (lecto NSW, fide J & H).

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.
