A tabular summary, by family, of the 56,431 computerized names of those native and naturalized plant taxa included in the “Synonymized checklist of the vascular flora of the United States, Canada and Greenland” (including Alaska, Hawaii, Puerto Rico and the U.S. Virgin Islands) indicates a flora of 21,588 species in 2,921 genera in 254 families. There are also 740 named hybrids and, under current concepts, 2,491 subspecies and 8,008 varieties in our flora. There are 20,429 pertinent or “manual level” synonyms, with the number of synonyms exceeding the number of accepted names in many families (especially those families of high agricultural, horticultural or other economic importance).
