The Jardin botanique de Cayenne is a botanical garden located at the end of the Avenue Charles de Gaulle, adjacent to the university, in Cayenne, French Guiana. The garden measures 3 hectares.[2] Although the Conseil Général de la Guyane states that the garden, formerly the Jardin du Roi (King's Garden), was established in 1879,[2] there are earlier references to a botanical garden in Cayenne.[3] It now contains a statue of politician Gaston Monnerville (1897-1991).[4]
