Flora of Great Britain and Ireland
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 has been compiled by the Botanical Society of Britain and Ireland. The lists (spread across multiple pages due to size) give 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).

 List of the vascular plants of Britain and Ireland (ferns and allies) covers ferns and allies (Lycopodiopsida, Equisetopsida and Pteridopsida)
