Viola pinetorum
Viola pedatifida
Flowers of Viola pinetorum have been observed to close up in late afternoon then fully reopen the following morning.
Although E. O. Wooton and P. C. Standley (1915) reported Viola pinetorum from New Mexico, the plant was probably V. nuttallii. K. W. Allred (2008) noted that V. pinetorum occurs in California; he did not recognize it in New Mexico.
Varieties 2 (2 in the flora).

Viola pedatifida was reported historically from, and recently rediscovered in, the Appalachian shale barrens of Virginia (T. Wieboldt, pers. comm.).
Viola pedatifida reportedly hybridizes with V. sororia (= V. ×bernardii Greene).
