Seaweeds

With some 1020 figures in 263 colour plates.
This guide will help in the identification of marine algae (macroalgae, seaweeds) without requiring special knowledge of the subject and technical aids, such as a microscope. For a person interested in nature with a general interest in and knowledge of biology, a direct comparison of seaweed material with the original colour images herein will be useful in recognising the essential morphological chararcteristics of genera and/or species. The acommpanying text is intended to support this, and is essentially reduced to a description of morphological characteristics that can be seen with the unaided eye (although a small magnifying lense is helpful in some cases). This is supplemented by additional information, particularly on habitat and geographical distribution.
