The results of two floristic studies of King George County, Virginia, are combined into an annotated checklist. Field work was initiated in 1983-84 with a study of Caledon Natural Area, a 2,500-acre tract with 3.5 miles of frontage on the Potomac River. Collecting resumed in 1991 and 1992 to include other portions of the county drained by the Potomac River. The study area contains a wide variety of habitats including dry upland woods, mesic ravines, low elevation river flats, beaches, swamps, marshes, and creeks; creeks and marshes include both brackish and freshwater environments.

An inventory of the vascular flora of nine of eleven units of Richmond National Battlefield Park was compiled from 1985 to 1987. Each site was visited during the growing season in two to four week intervals; plant species were identified and recorded in the field and/or collected for later study. A total of 761 different species were identified in the surveyed units, and 2487 individual records of species per particular park unit were noted. Twenty-three percent of the flora consists of exotic species, largely from Eurasia. Voucher specimens are housed in the herbaria of the University of Richmond and Virginia …

University Of Richmond Herbarium, W. John Hayden
Biology Faculty Publications
The Department of Biology at the University of Richmond, Richmond, Virginia, maintains an herbarium of approximately 15,000 specimens. Although recently assigned the acronym URV, this collection has not yet been included in Index Herbariorum and, consequently, few botanists outside of Virginia are aware of its existence. This note provides a brief account of the history of URV, a summary of its contents, and a short bibliography of works pertaining to the collection.
