The objective of this study was to create a comprehensive record of the vascular plants of Shenandoah County, Virginia. Specimens were collected from the field during the 2011 growing season (March 21 – October 27), and for part of the 2012 growing season (March 22 – May 30). Local herbaria of James Madison University (JMUH), Bridgewater College (BDWR), Eastern Mennonite University (HAVI) and Lord Fairfax Community College (LFCC) were also searched for pre-existing specimens. The results of the study were compared to records of the Digital Atlas of the Virginia Flora (2012), which currently maps the distribution of vascular plants in Virginia. The survey resulted in 53 new additions to the county record, including 2 new state records for Virginia. The combined results of the field collections, herbarium specimens, and Digital Atlas comprise a total of 1,299 species in 563 genera and 143 families. Of these, 57 species are ferns and fern allies, 8 are gymnosperms, 322 are monocots and 912 are dicots. The records represent 1,014 native species to Virginia, 268 introduced, and 14 unspecified by the Digital Atlas. Voucher specimens of the new field collections are housed in the James Madison University Herbarium.
