These handy, accurate, and easily used keys to fruit and twig identification are the only guides of their sort with photographs--over 350 of them, of nearly every twig and fruit described--making them especially valuable to the novice. The fruit key (dealing with both deciduous trees and evergreens) begins with a concise introduction, explaining simply and lucidly the process of seeding, and identifying the various organs involved: the cones and flowers, and their component parts and variations. Next the various types of fruits are described--drupe, berry, pome, legume, follicle, capsule, achene, samara, nut--and fruiting habits, followed by a synoptic summary of fruit types. The introduction to the twig key tells in plain language the process of growth and its relation to twig morphology through leaf scars, branch scars, buds, etc. For the benefit of the unwary, poison-ivy, poison-oak and poison-sumac are immediately and fully described. Identification in both books is easy. There is a pair of alternative descriptions of each aspect of the specimens. Your choice of the fitting one leads you automatically to the next proper pair. At the end of the chain is the name of your specimen and, as a double check, a photograph. More than 120 different fruits and 160 different twigs are distinguished. This exceptional work, widely used in university courses in botany, biology, forestry, etc., is a valuable tool and instructor to the naturalist, woodsman, or farmer, and to anyone who has wondered about the name of a leafless tree in winter or been intrigued by an interestingly shaped fruit or seed.

To many plant lovers winter seems like lost time, but a glance at the twigs of trees and shrubs shows that this does not need not be the case. In contrast to other life forms, trees and shrubs do not die aboveground, but enclose their shoots for the next year in buds, presenting many characters which hardly change over time. Using these bud and twig characters, deciduous trees and shrubs can be classified reliably in winter, which is particularly important during planting time.Author Bernd Schulz's unrivalled masterpiece is a practical guide to identifying trees and shrubs in winter. Comprehensive and easy to use, it contains over 700 species identifiable via their winter buds and twigs. The illustrated identification keys are easy to use, and a summary set of keys are provided as an appendix. Detailed descriptions are accompanied with over 1,400 colour illustrations. 'This monumental taxonomic work is one reference work that will help us all to be more confident in the identification of a comprehensive list of winter twigs and buds.Tony KirkhamHead of Arboretum, Gardens and Horticultural Services, Royal Botanic Gardens, Kew

Muenscher was an early Cornell botany professor known as the "Wizard of Weeds." This first update since 1950 of his classic volume on eastern North American botany updates the changing nomenclature--the bane of many students, amateurs, and professionals--applied by the International Botanical Congress. There are comprehensive and field-oriented keys to genera and species, and a systematic list of species in the keys. Includes the preface to the 1922 edition, a glossary, diagrammatic guide to terms (the text's only visuals), and a briefly annotated bibliography. Cope is also a Cornell U. botanist.
