This catalogue, which integrates nearly 35,000 records of benthic marine algae from the Indian Ocean into a taxonomic classification comprising 3,355 specific and infraspecific taxa in 629 genera, will greatly facilitate future work in this region. The bibliography of 4,000 references is the largest list of phycological literature ever published. The extensive taxonomic and nomenclatural notes are of paramount importance.

Wynne''s "Checklist revision" is a compilation of the taxa of benthic marine algae occurring in the broad area of the tropical and subtropical Western Atlantic Ocean. It thus covers the region from North Carolina to southern Brazil, which is the same domain as the 1960 flora of W. R. Taylor. It includes a total of 1,227 species of benthic marine algae: 763 species of red algae, 168 species of brown algae, and 296 species of green algae. There are also Notes in regard to specific information for some of the taxa treated, where appropriate. This publication includes an extensive bibliography of pertinent literature for the period following the publication of the first checklist in 1986. The Checklist includes a Table of geographic regions (countries in the region covered and coastal States of the southeastern USA) listing the literature. Five figures of the coastal regions treated are also provided.
