Flora of Virginia Name/Status
Calystegia sepium (L.) R. Br.
Infraspecific taxonomy in Calystegia sepium has been controversial and confusing. Brummitt (Kew Bull. 35:327-334 (1980)) recognized five subspecies of C. sepium that could be attributed to Virginia (see synonymy above). Their status and distributions are presently unknown, and they will be difficult, if not impossible to map, without better character sets to work with. For those who wish to delve deeper into this polymorphic species, the Flora of Virginia provides brief descriptions of the supposedly diagnostic characters for each subspecies. Flora of the Southeastern U.S. is in the process of transferring all Calystegia spp. back into Convolvulus, and also has a key that may be useful. However, several of the combinations in Convolvulus have not been formally published, so we are holding off on evaluating and/or following this change until the work is completed.
This species (as broadly interpreted) occurs in a wide range of natural and disturbed habitats but has weedy tendencies; recorded from mesic upland forests, floodplain forests, stream banks and bars, tidal freshwater and oligohaline marshes, dune grasslands, interdune swales, old fields, cultivated fields, fencerows, disturbed alluvial soil, and other ruderal habitats. Common throughout.
