Manual of the Trees of North America (Exclusive of Mexico) 2nd ed.

A practical identification manual covering the woody trees found in North America outside Mexico, organized by botanical families and genera with analytical keys and conspectuses that guide readers from leaf characters to species. Entries give concise botanical descriptions, geographic range by eight vegetation regions, and illustrative plates; nomenclature follows contemporary botanical conventions. The volume emphasizes diagnostic characters of leaves, flowers, and fruit, includes taxonomic notes and recent name changes, and provides a tool for both field determination and further study of distribution, variation, and silvicultural questions.
