.
in 1848, at species rank as Euphorbia eremophila. In 1977 David Hassall demoted it to a variety of E. tannensis
. At the same time he did the same thing for E. finlaysonii, and since he felt these two to be more closely related to each other than either is to the type material of E. tannensis, he erected E. tannensis subsp. eremophila to hold both varieties. Thus this subspecies comprises two varieties: E. tannensis var. eremophila
and E. tannensis var. finlaysonii
