This very impressive volume is a revision of the 1974 classic Agriculture Handbook 450-Seeds of Woody Plants in the United States. The 386 genera covered are more than double that of the previous edition. The treatment includes important timber and wildlife species, many small trees, shrubs and vines useful in landscaping, and selected Asiatic taxa. Most literature citations from Handbook 450 are not repeated, but over 1,000 new citations from the last two decades have been added.
