L. E. McKinney (1992) considered Viola novae-angliae to be a variety of V. sororia; N. L. Gil-Ad (1997) treated it as a distinct species. H. E. Ballard and S. C. Gawler (1994) also considered V. novae-angliae distinct and suggested it might be a hybrid between V. sagittata and V. sororia. Viola novae-angliae appears to have a close affinity with V. sororia; we recognize them here as separate species.
