Discussion

Variety mohrii is recorded with certainty only east of the Mississippi River; it is perhaps very rare. In the co-type, Beadle 236A, the inflorescences may be glabrous or pilose The relatively small, short leaves, small flowers, 3–5 styles, and broadly elliptic to suborbiculate extension-shoot leaves clearly mark var. mohrii as a member of the reverchonii group. Variety mohrii is notable for its strongly and sharply serrate leaf margins.
