B. L. Turner (1994) distinguished three varieties based primarily on perianth and fruit size. The robust, large-flowered var. villosa, intergradient with var. incarnata, is conspicuous in the field in its extreme, but difficult to distinguish on many herbarium specimens if geographic origin is unknown. This large-flowered variety is occasionally immediately sympatric with small-flowered phases of var. incarnata.
