Some types of "native flora" actually have been introduced centuries ago by people migrating from one region or continent to another, and become an integral part of the native, or natural flora of the place to which they were introduced.
Beberapa jenis "flora asli" sebenarnya telah diperkenalkan berabad-abad lalu oleh orang-orang yang bermigrasi dari satu wilayah atau benua ke benua lain dan menjadi bagian integral atau alami dari flora asli.
