Abstract
Veronica agrestis L. (field speedwell or green field speedwell), a member of the Scrophulariaceae, is a small, weedy, prostrate annual with blue or white flowers (Gleason and Cronquist 1991). Until recently, its distribution included most of the eastern half of the United States and the southern two-thirds of the Great Plains, but not South Dakota (http://plants.usda.gov/java/profile?symbol=VEAG &photoID=veag_001_avd.tif, accessed 5 February 2007). Neither the Great Plains Flora Association (1986) nor Van Bruggen (1996) includes this species in the flora of South Dakota; however, the former has it naturalized in southeastern Nebraska and in Iowa (Great Plains Flora Association 1986). In May, 2004, I found two populations of field speedwell in Mitchell, Davison County, South Dakota, each growing in disturbed soil about 4.5 km apart. Both were in fruit.
