This was a new term for me so I thought I would include some information from Wikipedia for you. Because the Canary Islands are a community of Spain and I’ve been to Morocco four times, my country count will stay at 88 of the 193 United Nations Member States. If you count territories such as Wales, Scotland, Svalbard, etc. I have 124 out of 330.
Macaronesia is a collection of four volcanic archipelagos in the North Atlantic Ocean, off the coast of North Africa and Europe. Each archipelago is made up of a number of Atlantic oceanic islands, which were formed by seamounts on the ocean floor whose peaks have risen above the ocean's surface.

Each of the archipelagos is a distinct political entity: the Azores and Madeira are autonomous regions of Portugal, the Canary Islands is an autonomous community of Spain, while Cape Verde is a sovereign state and member of the United Nations. Politically, the islands belonging to Portugal and Spain are parts of the European Union, while Cape Verde is a member of the African Union. Geologically, most of Macaronesia is part of the African tectonic plate. The Azores are located in the triple junction between the Eurasian, African, and North American plates.
The name Macaronesia was originally used by Ancient Greek geographers to refer to any islands west of the Strait of Gibraltar. It is derived from the Greek words meaning 'islands of the fortunate'. The term fell out of use until it was revived in 1917 with its current meaning.
The name is occasionally misspelled "Macronesia" in false analogy with Micronesia, an unrelated group of archipelagos in the Pacific Ocean whose name is also derived from Greek.
The islands of Macaronesia are volcanic in origin and are thought to be the product of several geologic hotspots. Due to the geographic location, varied relief and altitudinal ranges, the Macaronesian mountains represent a wide range of climates. These climates include oceanic, Mediterranean, and humid subtropical climates in the Azores; the tropical savanna climates in Madeira; the desert and semi-desert climates in the Canary Islands; and a tropical climate in Cape Verde.

In some locations, there are variations in climate due to the rain shadow effect. The laurisilva forests of Macaronesia are a type of mountain cloud forest with relict plant species of a vegetation type that originally covered much of the Mediterranean Basin, when the climate of that region was more humid. These plant species, many of which are endemic, have evolved to adapt to the islands' variable climatic conditions.
The Macaronesian islands have a biogeography that is unique in the world. They are home to several distinct plant and animal communities. Notably, the jumping spider genus Macaroeris is named after Macaronesia. Because none of the Macaronesian islands were ever part of any continent, all of the native plants and animals reached the islands via long-distance dispersal. Laurel-leaved forests, called laurisilva, once covered most of the Azores, Madeira, and parts of the Canaries at an altitude of between 1,300 and 3,900 ft, the eastern Canaries and Cape Verde being too dry.
These forests resemble the ancient forests that covered the Mediterranean Basin and northwestern Africa before the cooling and drying of the ice ages. Trees of the genera Apollonias, Clethra, Dracaena, Ocotea, Persea, and Picconia, which are found in the Macaronesian laurel forests, are also known, from fossil evidence, to have flourished around the Mediterranean before the ice ages.
