The Azores are a group of islands in the North Atlantic Ocean, west of the Iberian Peninsula. They are home to dozens of endemic species and subspecies of vascular plants. Although the Azores are politically part of Portugal, the World Geographical Scheme for Recording Plant Distributions treats the Azores as a distinct botanical country. The archipelago are part of Macaronesia, a biogeographical region which also includes the Canary Islands, Cape Verde Islands, Madeira, and the Selvagens.
