Calyx 5-lobed, scarcely accrescent, slightly zygomorphic to 2-lipped; tube (11–)13(–15)-veined, ± hairy inside near the mouth; posterior lip 3-lobed; anterior lip 2-lobed, divided to the base, with the lobes mostly longer and narrower
Morphology Reproductive morphology Flowers Corolla
Corolla 2-lipped; posterior lip emarginate; anterior lip almost flat, 3-lobed
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 4, ascending under the posterior corolla lip; thecae divaricate, separated by a short connective

Note
In most other Floras and systematic works, the tropical African species of Micromeria are included in the genus Satureja L. With new generic concepts, Satureja sensu stricto is not native in tropical Africa.
