Discussion | 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). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
