Michael (1997a) recognised Verbena officinalis var. africana and Verbena officinalis var. gaudichaudii at the rank of species, however, these taxa and other taxa are here included within Verbena officinalis at the rank of variety because they differ chiefly in the size of the spikes and flower parts and the dentation of their leaves, which are features that display intermediates between the taxa (Munir 2002).
Verbena officinalis is represented in Victoria by five varieties, two of which are most likely native and three introduced.
