The original, and best "pocket guide" for the experienced enthusiast to the flora of the British Isles in the form of a Key. Detailed, exact text with illustrative drawings, now updated in a friendly paperback format. This is the key to check out your dodgy identifications in the field, and at home. Use with a book of colour illustrations, safely quote it in your learned text for maximum cred.... Enjoy.
