The most authoritative, complete reference to the vascular plants of North America ever produced, containing a checklist with synonymy of all 28 000 species, subspecies and varieties. A distribution map for any one of the 35 000 families, genera, species, and infraspecific taxa can be displayed at the click of a mouse button. The Synthesis is a universal checklist for any state or province in North America.
Advance praise:
"A must-have work for anyone with a serious interest in the systematics and/or floristics of North American vascular plants. It will serve as the essential starting point for any floristic or regional systematic work on North American plants well into the next millennium."
- Raymond Cranfill, Taxon
