This second volume of the magnificent compendium exhaustively describes and classifys the ferns, fern allies, and gymnosperms of North America. Covering over two dozen fern and half a dozen gymnosperm families, they survey fern species of both ecological and horticultural importance and review such gymnosperm taxa as the conifers (the dominant trees in many forests as well as important timber plants) and cycads, which display significant evolutionary features. In all, the volume assembles 509 species of ferns and fern allies and infraspecific taxa in 70 genera.

Flora of North America, Volume 22, is the first of five volumes covering monocots in North America north of Mexico. The volume comprises many groups of acquatic plants and the North American relatives of groups that have their richest number of species in the New World tropics. Included among the treatments are the rush family (Junaceae), which include important indicator species in wetland habitats, the cat-tails (Typhaceae), spiderworts (Commelinaceae), aroids (Araceae), and pondweeds (Potamogetonaceae). Thirty families are included in this volume, representing a diverse range of plant forms - from marine Zosteraceae (eel-grasses) to stately Arecaceae (palms) and the naturalised exotic Zingiberaceae (gingers), Heliconiaceae (heliconias) and Musaceae (bananas).

To be published in 14 volumes over the next 12 years, this long-awaited synoptic compendium represents the first and only comprehensive taxonomic guide to the extraordinary diversity of plant life blanketing our continent north of Mexico--including Greenland and the St. Pierre and Miquelon islands. The collaborative effort of more than 30 major U.S. and Canadian botanical institutions, it revises and synthesizes literally thousands of floristic monographs and regional floras published over the last three centuries. But more than that, it distills the original herbarium, laboratory, and field work of hundreds of contributors--all of them leading botanists and taxonomic authorities who have joined forces to develop this century's premier tool for identifying, understanding, and conserving North America's priceless floristic heritage. Concise, easy to use, and beautifully bound and illustrated, Flora of North America is an indispensable working resource for botanists, conservationists, ecologists, agronomists, foresters, range and land managers, horticulturists,--anyone with a serious interest in the distribution, habitat, morphology, and survival of the wide-ranging plant life around us. Each of its taxonomic volumes brings together the full spectrum of critical botanical data, from basic descriptions to chromosome numbers. The entries also correct erroneous information, qualify misapplied variant names, and note known hybridizations. Findings derived from recent experimental work and from numerical taxonomy are incorporated, and to assure accuracy, these data have been extensively reviewed and tested by cooperating taxonomic specialists. Volume 1 consists of a series of introductory essays by nearly two dozen noted botanical authorities. Among the topics covered are the transformation of North American plant life since the end of the Mesozoic era some 70 million years ago; the influence of geographic, climatic, and soil factors; the impact of human cultivation; great naturalists and their contributions to botany and floristics since the age of Columbus; and approaches to plant classification, with particular attention to the evolutionarily unique pteridophytes and gymnosperms that are covered in Volume 2.

North American Wildland Plants is the sixth edition of North American Range Plants. This comprehensive reference contains the salient characteristics of the most important wildland plants of North America and will help individuals with limited botanical knowledge as well as natural resource professionals to identify wildland plants. The two hundred species of wildland plants in this book were selected because of their abundance, desirability, or poisonous properties. ø Each of the illustrations has been enhanced to maximize the use of this book as a field guide. Each plant description includes characteristics for identification, an illustration of the plant with enlarged parts, and a general distribution map for North America. Each species description includes nomenclature; life span; origin; season of growth; inflorescence, flower or spikelet, or other reproductive parts; vegetative parts; and growth characteristics. Brief notes are included on habitat; livestock losses; and historic, food, and medicinal uses.
