感觉这几个群岛不属于地理上的,但是维基上:
The name is derived from the Greek words for "islands of the fortunate" μακάρων νῆσοι makárōn nêsoi, a term used by Ancient Greek geographers for islands to the west of the Straits of Gibraltar. Macaronesia is occasionally misspelled "Macronesia" in false analogy with Micronesia, an unrelated Pacific archipelago containing, among other nations, a country of the same name.
