Maytenus
Maytenus  is a genus of flowering plants in the family Celastraceae. Members of the genus are distributed throughout Central and South America, Southeast Asia, Micronesia and Australasia, the Indian Ocean and Africa. They grow in a very wide variety of climates, from tropical to subpolar. The traditional circumscription of Maytenus is paraphyletic, so many species have been transferred to Denhamia, Gymnosporia, Monteverdia, and Tricerma. Selected species

Cultivation and uses
Maytenus boaria and Maytenus magellanica are the most known species in Europe and the United States because these are the most cold-tolerant trees of this mostly tropical genus. The bark of Maytenus krukovii has a variety of documented medicinal properties; it is also sometimes admixed into decoctions of ayahuasca. References
