Leonotis

Leonotis is a genus of flowering plants in the family Lamiaceae. 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.

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

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

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

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