Discussion
Subspecies carolina is characterized by short, weak, spreading or erect stems armed with erect, flat or, infrequently, subulate, paired infrastipular prickles, and is common in the eastern and southeastern United States, corresponding to the Austroriparian Subprovincial Element (S. P. McLaughlin 2007). To the west, it occurs less frequently in lowland areas and is replaced elsewhere in drier areas by subsp. subserrulata; intergrades are found in eastern Midwest regions. Subspecies carolina is relatively rare in Arkansas, Kansas, Louisiana, Oklahoma, and Texas.
