This book places grapes in the context of their family, the Vitaceae. It begins by focusing on the relationship of the family to other angiosperms and the interrelationships and characteristics of its genera. Two chapters emphasize the structure and development of its major vegetative and reproductive characteristics. Keys and illustrated descriptions for 19 North American species including 10 Vitis are provided. The three chapters on Vitis begin with a brief history of grape growing, with emphasis on North America. There is an illustrated life history of grape, following the two-year cycle from bud initiation to fruit maturity. The final chapter discusses the history of grapevine identification in North America, concluding with descriptions and illustrations of 30 important North American cold climate cultivars. The book is a general resource for understanding the growth, development, life history, and identification of grapes and the Vitaceae.
