Approximately 50 plants were found growing in a seasonally ponded area along the southeast perimeter of the site among the following mixture of species: Persicaria maculosa Gray, Andropogon virginicus L., Rumex crispus L., Eleocharis palustris (L.) Roem. & Schult., Portulaca oleracea L., Digitaria ischaemum (Schreb.) Schreb. ex Muhl., and Bidens aristosa (Michx.) Britton, 14 July 2009, N. McGoff and N. Zinn. Voucher specimen deposited at the Massey Herbarium at Virginia Tech, Blacksburg, Virginia (VPI 105248).
Significance. This is the first account of bog bulrush [Schoenoplectus mucronatus (L.) Palla] in Virginia and, to the best of our knowledge, the first record of this species within the South Atlantic states (Smith 2002, Virginia Botanical Associates 2009, United States Department of Agriculture-Natural Resources Conservation Service [USDA-NRCS] 2009). Bog bulrush is native to Africa and Eurasia and is listed as a problematic weed in 43 countries, presumably owing to its prolific colonization of rice fields and resistance to herbicide treatment (Smith 2002, Washington Noxious Weed Control Board 2010).
