Flora of North America Volume 27 will be the first volume of three on the bryphytes (mosses, hornworts, and liverworts). Thirty-five authors treat the first half of the mosses, including 32 of the acrocarpous families, with introductory chapters on bryophyte morphology, the history of North America floristic bryology, and economic uses. The 84 species of sphagnum, of considerable economic importance, are fully treated. The number of taxa total 37 genera and 621 species. The taxa are fully described and keyed, illustrated with an estimated 136 panels of detailed line drawings of two or more species each, and geographic distributions are provided at the province and state level. This is the first installment of a full compilation of the mosses for North America since A. J. Grout's Moss Flora of North America of 60 years ago, and will be an invaluable reference.

The present treatment constitutes a taxonomic study of the green and brown benthic marine algae currently known in the northern Gulf of California. In all, 133 species were found: 4 classes, 7 orders, 13 families, 20 genera, and 63 species of Chlorophyta and 9 orders, 15 families, 26 genera, and 70 species of Phaeophyceae. The systematic account is a guide to the identification of marine algae from the northern Gulf of California, with the accepted name, keys, and descriptions of the orders, families, genera, and species. The date, place, and author(s) of valid publication of each taxon are cited. The current name for each species is given along with its basionym, type locality, synonyms, relevant taxonomic studies, habitat, and distribution in the Gulf of California and in the Pacific Ocean. Illustrations are provided for most species. A remarks section includes additional information on taxonomy, nomenclature, ecology, and/or other problems or facts of interest. In addition to reviewing the taxonomic phycological literature pertinent to the Gulf of California and Pacific México, new records and distribution extensions are given. Four new sections of Sargassum subgen. Sargassum are proposed: S. sect. herporhizum E. Y. Dawson ex J. N. Norris, S. sect. johnstonii E. Y. Dawson ex J. N. Norris, S. sect. lapazeanum E. Y. Dawson ex J. N. Norris, and S. sect. sinicola E. Y. Dawson ex J. N. Norris; five new combinations are made: Desmarestia munda subsp. mexicana (E. Y. Dawson) J. N. Norris, Epicladia condensata (Setchell et N. L. Gardner) J. N. Norris, Epicladia mexicana (Setchell et N. L. Gardner) J. N. Norris, Hincksia bryantii (Setchell et N. L. Gardner) J. N. Norris, and Sargassum sinicola subsp. camouii J. N. Norris et Yensen. One new species, Sporochnus neushulii J. N. Norris, is described.

This comprehensive synthesis of our knowledge of the biostratigraphy of marine plankton is the work of an international team of eighteen authors. It covers all the major fossil groups that can be used to date sediments and rocks in the time interval Late Mesozoic to Holocene. Altogether more than 3200 taxa are considered, almost all of which are illustrated and depicted on range charts, making the book a valuable work of reference in the earth sciences. For ease of reference by specialists interested in either calcareous or non-calcareous microfossils, the original work is now divided into two independent volumes. Volume 2 describes siliceous and other non-calcareous microfossils, covering radiolaria, diatoms, silicoflagellates, dinoflagellates and ichthyoliths.
