"The object of this volume is to present a systematic and descriptive account of the shrubs of California which will serve as a working manual for their identification by the forester, ranger, traveler, vacationist, teacher, landscape designer, gardener, and student of nature. While primarily planned for the use of the general public, the book has been written to serve also the professional botanist who is interested in the native shrubs of California"--Preface (page ix).

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.
