Mentha is a genus of plants in the family Lamiaceae. The exact distinction between species is unclear; it is estimated that 13 to 24 species exist. Hybridization occurs naturally where some species' ranges overlap. Many hybrids and cultivars are known.
Mentha pulegium, commonly (European) pennyroyal, or pennyrile, also called mosquito plant and pudding grass, is a species of flowering plant in the mint family, Lamiaceae, native to Europe, North Africa, and the Middle East. Crushed pennyroyal leaves emit a very strong fragrance similar to spearmint. Pennyroyal is a traditional folk remedy, emmenagogue, abortifacient, and culinary herb, but is toxic to the liver and has caused some deaths. European pennyroyal is related to an American species, Hedeoma pulegioides. Though they differ in genera, they share similar chemical properties.
Myoporum is a genus of flowering plants in the figwort family, Scrophulariaceae. There are 30 species in the genus, eighteen of which are endemic to Australia although others are endemic to Pacific Islands, including New Zealand, and one is endemic to two Indian Ocean islands. They are shrubs or small trees with leaves that are arranged alternately and have white, occasionally pink flowers and a fruit that is a drupe.

It is native to the western Mediterranean Sea region, growing naturally from southwestern France to the Iberian Peninsula, and south to Azores, Morocco and Algeria.

The plants were associated due to their shared high pulegone content, which gives them both a distinctive, strong aroma.

Gahnia is a genus of sedges native to China, Southeast Asia, New Guinea, Australia, New Zealand and a number of Pacific Islands. The common name is due to the toothed margins. It often forms tussocks.

Mentha atrolilacina, or slender mint, is a species within the Mentha (mint) genus, endemic to southeastern South Australia. It has been identified only within the Honans Native Forest Reserve, near Mount Gambier, South Australia.
