The taxonomy of the genus Mentha has been in a state of flux, with more than 3000 names
published since 1753. On the basis of a phylogenetic analysis of morphology, chromosome
numbers, and major essential oil constituents, the genus Mentha is redefined to include
18 species and 11 named hybrids, placed in four sections. Mentha cunninghamii is excluded
and may be more closely paired with the genus Micromeria (s.l.). An enumeration of the taxa,
with more important synonymy, follows a key to the species.
