A field key to the British Brown Seaweeds

This AIDGAP identification key is designed to allow non-specialists to identify the majority of British macroscopic (larger than 1cm) brown seaweeds in the field, most to species level where this is possible without a microscope. Littoral, sublittoral and rare species are all included to help with brown seaweed identification. A full glossary is appended, and numerous thumbnail sketches are incorporated in the text to help ease-of-use. All plants are fully illustrated and an introductory section describing the ecology of the brown seaweeds will help in interpreting patterns of distribution on the seashore.
