The flora of Great Britain and Ireland is one of the best documented in the world. There are 1390 native species and over 1100 well-established non-natives documented on the islands. A bibliographic database of the species is compiled by the Botanical Society of Britain and Ireland. Because of the size of the list, it is spread across multiple pages.
The remaining parts cover the flowering plants (Magnoliopsida):
The list gives an English name and a scientific name for each species, and two symbols are used to indicate status (e for extinct species, and * for introduced species).
Lists of the plant species found in Ireland can be found at Irish Species Register The lists on this site are based on these "Key references"
