Comments
This taxon has been widely lumped into a broad concept of Calystegia sepium, and most Virginia specimens have still not been segregated from other taxa of the complex. The current map is therefore very incomplete.

A useful key with diagnostic characters of this taxa can be found in the Flora of the Southeastern U.S., which is in the process of transferring all Calystegia spp. back into Convolvulus. 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.
Habitat
The few confirmed specimens are mostly from the Coastal Plain. Habitats include dunes and upper beaches, brackish marshes, tidal river shores, and sandy fields. Its overall status is poorly known but plants may be common in local areas where found.
Native Status
Native
