This Flora of Cornwall is the most comprehensive so far. It is based on a survey of every kilometre square since 1999. It covers 3018 taxa and includes over 1200 distribution maps and more than 1700 photographs. It is based on 2.25 million flowering plant and fern computerised records. It also includes a chapter dealing with drift seeds (disseminules) written by Paul Gainey and the extensive bramble section is written by Keith Spurgin. Further sections include the effects of: climate, geology, soils, topography, mining, quarrying, and agriculture. In addition, there is information on vegetation history, key habitats, botanical regions, recording history, losses and gains, and rare and/or threatened plants.
"[...] I have a few quibbles with the design. [...] That said, this is a state-of-the-art county flora that reflects great credit on Cornwall’s tight team of field botanists, and on the expertise, dedication and computer know-how of its author."
