L. E. McKinney (1986) considered the differences between Viola walteri and V. appalachiensis to be minor, choosing not to recognize the latter. H. E. Ballard and D. E. Wujek (1994) provided evidence to continue recognition of V. appalachiensis.

Variety appalachiensis is reported to hybridize with Viola striata (= V. ×wujekii H. E. Ballard).
