Manual of Vascular Plants of Northeastern United States and Adjacent Canada. 2nd edition

Book by Gleason, Henry A., Cronquist, Arthur The first edition of Gleason's Manual of Vascular Plants. . .(1963) is still often cited as the authority for plant taxonomy. This new edition has a more useful arrangement of plant families; the treatment of species was retained except for many corrections and revisions suggested by the recent literature, other botanist's comments, or the author's own experience. It contains 100 more pages than the first edition, slightly smaller print, the same general dimensions, and similar binding. Like the first edition it contains a list of abbreviations, a helpful glossary, general keys to families, followed by descriptions of orders and families, keys to genus and species, and an index of common and Latin names. One additional aid is the list of abbreviated names of some of the more frequently cited botanical authors. Another taxonomic authority, Asa Gray's Gray's Manual of Botany, has not been revised since its eighth (centennial) edition in 1950. Gleason's revision is strongly recommended for all botany collections serving students at any academic level with interest in the flora of northeastern United States.-E. Williams, Vassar College--Choice Review This second edition of the Manual was completely revised by Cronquist, the taxa rearranged according to his phylogenetic system, and the nomenclature updated. The general keys--long known for their ease of use--have been revised, new synoptic keys added, and the glossary expanded. This edition reflects an effort to incorporate into a single comprehensive account the results of modern taxonomic research on the flora of the area covered, with due regard to all past accounts, all in the light of Cronquist's critical evaluation. The aim is to make it possible for the user to correctly identify a plant using only a hand lens or occasionally a dissecting microscope. This corrected edition was first issued in 2004 This manual is intended to facilitate the identification of vascular plants growing wild in the northeastern United States and adjacent Canada. The part of the United States covered extends from the Atlantic Ocean west to the western boundaries of Minnesota, Iowa, northern Missouri, and southern Illinois, south to the southern boundaries of Virginia, Kentucky, and Illinois, and south to the Missouri River in Missouri. In Canada the area covered includes Nova Scotia, Prince Edward Island, New Brunswick, and the parts of Quebec and Ontario lying south of the 47th parallel of latitude
