Book Description
The PA Flora Database (PFD) has its roots in the work of Edgar Wherry, John Fogg, Jr., and Herbert Wahl, the "Atlas of the Flora of PA", pub. by the Morris Arboretum of the Univ. of PA. Over a period of 40 years, Wherry and his colleagues gathered data from the major PA herbaria and manually placed a quarter of a million dots on over 3,500 maps, which are reproduced in this volume. The checklist of included taxa has undergone extensive review to reflect recent taxonomic and nomenclatural revisions. Recent discoveries have been added and distribution data has been updated. This volume also includes collections made in the 1990s in conjunction with the PA Natural Diversity Inventory. Extensive illustrations. Reprinted 1996.

Book Description
This is by far the best and most comprehensive manual and illustrated guide to native and naturalized vascular plants—ferns, conifers, and flowering plants—growing in aquatic and wetland habitats in northeastern North America, from Newfoundland west to Minnesota and south to Virginia and Missouri. Published in two volumes, this long-awaited work completely revises and greatly expands Norman Fassett’s 1940 classic A Manual of Aquatic Plants, yet retains the features that made Fassett’s book so useful. Features include: * coverage of 1139 plant species, 1186 taxa, 295 genera, 109 families * more than 600 pages of illustrations, and illustrations for more than 90% of the taxa * keys for each species include references to corresponding illustrations * habitat information, geographical ranges, and synonomy * a chapter on nuisance aquatic weeds * glossaries of botanical and habitat terms * a full index for each volume Wetland ecologists, botanists, resource managers, public naturalists, and environmentalists concerned with the preservation of wetland areas, which are increasingly threatened, will welcome this clear, workable, and comprehensive guide.

Book Description
The field of plant taxonomy has transformed rapidly over the past fifteen years, especially with regard to improvements in cladistic analysis and the use of new molecular data. The second edition of this popular resource reflects these far-reaching and dramatic developments with more than 3,000 new references and many new figures. Synthesizing current research and trends, Plant Taxonomy now provides the most up-to-date overview in relation to monographic, biodiversity, and evolutionary studies, and continues to be an essential resource for students and scholars. This text is divided into two parts: Part 1 explains the principles of taxonomy, including the importance of systematics, characters, concepts of categories, and different approaches to biological classification. Part 2 outlines the different types of data used in plant taxonomic studies with suggestions on their efficacy and modes of presentation and evaluation. This section also lists the equipment and financial resources required for gathering each type of data. References throughout the book illuminate the historical development of taxonomic terminology and philosophy while citations offer further study. Plant Taxonomy is also a personal story of what it means to be a practicing taxonomist and to view these activities within a meaningful conceptual framework. Tod F. Stuessy recalls the progression of his own work and shares his belief that the most creative taxonomy is done by those who have a strong conceptual grasp of their own research.
