Discussion

Variety scariosa is an Appalachian entity that might justifiably be treated as distinct from vars. novae-anglieae and nieuwlandii at species level, as done by Shinners. It has shorter stems and smaller heads than vars. nieuwlandii and novae-angliae, and the transition in shape and size from basal to cauline leaves is more abrupt.
