Trevoa is a genus of actinorhizal plants; these dicotyledon flora are trees or small shrubs. The genus was first proposed by Miers in 1825, but was not fully described until 1830 by Sir William Jackson Hooker.[1] Genus members are notable for their ability to fix nitrogen. Species of this genus are generally found in the near coastal forests and arid shrubland of South America. Some species are localized in the mountains of central Chile; for example, the species Trevoa trinervis occurs in the La Campana National Park[2] and other proximate areas of central Chile.

Along with some related plants in the family Rhamnaceae, they fix nitrogen via root nodules which contain Frankia bacteria.[3] Other nitrogen-fixing genera in this family include Ceanothus, Colletia, Discaria, Kentrothamnus, and Retanilla.[4]

Taxonomy
