A Field Key to the British Brown Seaweeds

This handy dichotomous key to brown seaweeds is designed to be used in the field. It is accessible by beginners as it avoids technical jargon.

Pages 43
Coverage Most British macroscopic (larger than 1cm) brown seaweeds including littoral, sublittoral and rare species are included. Most are keyed to species, unless microscopy is required when they are only keyed to group.
Illustrations Thumbnail line drawings accompany the key, c. 60 species drawings at the back.
Identify In the field (also useful to examine with x8 or x10 hand lens).
Specimen Prep. Fresh specimens, in the field. Mature receptacles are needed for identification of some Fucus species, so must be examined at the appropriate time of year.
Difficulty The key concentrates on the easier species, leaving the more difficult as groups. The principal remaining problems are variability of Fucus species and saltmarsh forms (see p6). Brown seaweeds are easier to identify than their red cousins covered in the sister publication.
