Synonyms

Mentha micrantha, is a plant species in the genus Mentha, native to western Kazakhstan and southeastern Russia. The species was described in 1890 by botanist George Bentham.[3] Its epithet, micrantha, means "with small flowers."[4] It is unique among its genus as the only species that is an annual plant.[5][6]

Taxonomy

The proper classification of Mentha micrantha is contentious. Several taxonomy references, such as Plants of the World Online and the Global Biodiversity Information Facility, accept it as a distinct species.[7][3][8] A 2006 treatment of the genus Mentha however asserted it to be a variety of Mentha pulegium.[1]

Where treated as distinct, M. micrantha has been considered to belong to the section Pulegium within the Mentha genus.[5] This section associates it with plants such as M. pulegium as well as Mentha gattefossei.[9]

Description

Mentha micrantha is a small annual plant, growing erect, branched, square-shaped stems measuring from 12 to 30 centimeters high. Its leaves are almost entire, oblong or ovate in shape. It flowers in verticillasters 7 to 12 millimeters in length, producing bi-labiate corollas, pink, rose-lilac or purple in color.[2]

Distribution

Mentha micrantha is distributed throughout southeast Russia and western to central Kazakhstan.[1][10] It occupies steppe areas and sinkholes.[5][2] It is a hygrophyte, preferring wet soil conditions.[11]
