Rhamnus caroliniana var. mollis (type from Illinois, with leaves persistently soft-pubescent abaxially) has sometimes been recognized as a western/Ozarkian entity (for example, H. A. Gleason and A. Cronquist 1991), but intermediates and intergrades with the typical form (with leaves glabrescent abaxially) are as numerous as the extremes.
