The volume "Marine algae of the eastern tropical and subtropical coasts of the Americas" produced by W. R. Taylor in 1960 was a comprehensive treatment of the benthic seaweeds of this region and remains a useful compendium for the breadth of its coverage, its detailed descriptions, and excellent artwork. But in the 50 years since that floristic treatment, numerous regional treatments have appeared, many new taxa described, and many new records have been published.
