- Comments
- As traditionally interpreted, Cardamine pratensis is a circumboreal species with representatives in Eurasia and northern North America. Eurasian plants have pink flowers and upper-stem leaves sessile to decurrent on the rachis, while North American plants have white flowers with upper-stem leaves petiolate. The two have been variously lumped (as by FNA), treated as vars. (as by Cronquist and Fernald), or treated as species (as by Haines and Flora of the Southeastern U.S.). The appropriate rank remains unresolved and in need of modern phylogenetic study. Virginia plants are all white-flowered natives, so the varietal designation seems like an appropriate compromise for now.
- Habitat
- Seepage swamps, alluvial and tidal swamps, and beaver wetlands. Rare in the central Coastal Plain (Lancaster, Middlesex, and Gloucester counties); disjunct to the nw. mountains (Frederick County).
