Discussion

Variety pringlei is found throughout much of the range of the species, just reaching Quebec, but is absent in Virginia and North Carolina. Extreme forms are very distinct in appearance with their strikingly convex, broadly elliptic, usually shallowly incised leaves and often oblong fruit. Intermediates with var. coccinea are common.
