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. *
