Muenscher's keys to woody plants : an expanded guide to native and cultivated species /

"This major expansion and revision of W. C. Muenscher's popular reference work brings a wealth of botanical knowledge up to date in an easy-to-access format. Muenscher's Keys to Woody Plants enables its users to identify trees and shrubs in all seasons by means of diagnostic field characteristics including leaves, fruits, buds, twigs, and bark. The new and expanded version of this classic identification tool for horticulturists, botanists, foresters, and ecologists treats more than 300 genera and more than 1,100 species of woody plants found in the northeastern United States. This is more than double the number covered by Muenscher's sixth edition and includes almost 600 cultivated species."--BOOK JACKET.
