Horticulture has remained far behind in understanding of botanical principles. Recent phylogenetic (DNA-based) reorganization of higher plants has revolutionized taxonomic treatments of all biological entities, even when morphology does not completely agree with their organization. This book is an example of applying principals of botanical phylogenetic taxonomy to assemble genera, species, and cultivars of 200 vascular plant families of ferns, gymnosperms, and angiosperms that are cultivated for enhancement of human living space; homes, gardens, and parks. The emphases are on cultivated species but examples of some plants are often shown in the wild and in landscapes. In providing descriptions, it is assumed that students and other interested individuals have no background in general botany (plant characteristics), or nomenclature. Fundamental features of all plant groups discussed are fully illustrated by original watercolor drawings or photographs. Discussion of the families is grounded on recent botanical phylogenetic treatments, which is based on common ancestry (monophyly). Of course, phylogenetic taxonomy is not a new concept, and was originally based on morphological characteristics; it is the DNA-based phylogeny that has revolutionized modern biological classifications. In practical terms, this book represents the horticultural treatment that corresponds to phylogenetic-based botanical taxonomy, to which is added cultigens and cultivated genera and species. Hence, the harmony between horticultural and botanical taxonomy. This book covers phylogenetic-based taxonomy of Ferns, Gymnosperms, and Angiosperms (Monocots). A companion volume covers Angiosperms (Eudicots).

Each vol. is divided into 2 parts 1st-7th ed.: Dictionary catalog and Classified catalog; 8th-9th ed. have 3rd. part: Directory of publishers.

Updated edition of the classic botanical guide to the Great Lakes region

The mountainous Blue Ridge, perhaps the most botanically diverse region in the eastern United States, extends for more than five hundred miles, the bulk of the area falling within eighty-five counties of five states: Virginia, North Carolina, South Carolina, Tennessee, and Georgia. The area has attracted the attention of botanists for nearly two centuries, yet no comprehensive work has previously been available that catalogs its rich floristic abundance. Addressing the needs of professional and amateur botanists interested in the Blue Ridge, B. Eugene Wofford’s guide makes it possible to identify all the region’s native and naturalized plant life--representing 161 families, 726 genera, and 2,391 species and lesser taxa. Among the flora to be found in the Blue Ridge are a number of species that have been identified as rare or endangered. The volume contains an introduction instructing readers on the use of the guide; a glossary of terms with selected illustrations; a map of the region; a key to the major plant groups; and keys to the Pteridophyte, Gymnosperm, Monocot, and Dicot families as well as to genera, species and lesser taxa. The species and lesser taxa enumeration following each genus contains the scientific name, common name or names, general habitat preferences, frequency and area of occurrence, flowering or sporulating periods, and pertinent taxonomic and nonmenclatural synonyms. The keys for identification rely primarily on easily identified flowering or sporulating material and can be interpreted by all users, from beginners and amateurs to experienced professionals.
