Leonotis is a genus of flowering plants in the family Lamiaceae. [2] One species, Leonotis nepetifolia , is native to tropical Africa and southern India. It is naturalized throughout most of the tropics. The other species are endemic to southern + eastern Africa. [1] [3]

Contents

Leonotis was named by Robert Brown in 1810 in Prodromus Florae Novae Hollandiae et Insulae Van Diemen. [4] The name means "lion's ear".

The type for the genus is the specimen of Leonotis ocymifolia that was originally described as Leonotis leonitis. [5] It is a specimen of Leonotis ocymifolia var. ocymifolia. [3]

Leonotis leonurus and Leonotis nepetifolia seem to be mildly psychoactive, similar to cannabis albeit producing a far less potent and less intense "high".

  9. Leonotis pole-evansii Hutch. - Zambia

Taxonomy

Leonotis is a member of the subfamily Lamioideae. [2] Leonotis might be paraphyletic or even polyphyletic because Leonotis leonurus is not closely related to the other species. [6] In 2009, it was shown that Leonotis and 3 other genera are embedded in Leucas , [6] a genus of about 100 species. [2] If the 4 embedded genera were merged with Leucas, the expanded Leucas would have about 132 species.
