This does not pretend to be a review of what is probably the definitive horticultural classic since publication in 1923. Simply it is an announcement that this is a complete revision, to double length, with new material, and old material brought up to date. At 90, Dr. Bailey recently flew to the West Indies in search of plant specimens; his contact with the growing field of knowledge has never slackened. For identification of species of flora domestic to continental United States and Canada, this is indispensable. Species grown for food, ornament, utility; fruits, grains, grasses; greenhouse plants, ornamental shrubs, plants and garden flowers; more than 1,000 botanical terms, a key to the 194 natural families covered in the book- this gives the high spots of coverage.
