- Comments
- Many Virginia herbarium specimens have not been assigned to variety, and the present map is incomplete at the present time. See also the full species map for Calystegia spithamaea.
Tryon (Rhodora 1939) uses the name Convolvulus spithamaeus var. catesbeiana for the plant we call Calystegia spithamaea ssp. purshiana. Considerable nomenclatural confusion and taxonomic disagreement seems to exist in this group! In large measure, this plant is associated with the shale barren region of Virginia. - Habitat
- Dry, rocky open forests, woodlands, barrens, and clearings on shale, limestone, dolostone, and possibly other calcareous substrates. Infrequent in the mountains as a whole, but locally frequent in some parts of the Ridge and Valley region, and occasionally on the Blue Ridge.
