There are two types of endemism - paleoendemism and neoendemism. "Paleoendemism" means that a species used to live in a large area but now lives only in a smaller area. "Neoendemism" means that a species has recently appeared which is closely related to the main species or one that has formed following hybridization and is now classified as a separate species. This is a common process in plants especially those which exhibit polyploidy.
