Taxonomy Comments: Two questionable varieties are sometimes recognized.

T. subaspera var. montana ranges from sw. VA and c. WV south to nw. SC, n. GA, and se. TN, with disjunct occurrences in c. AL and Panhandle FL. Var. subaspera ranges from WV west to n. IL, south to se. TN, ne. AR, and s. MO, with disjunct occurrences in NC.
