- Comments
- Viola stoneana is a member of the Viola palmata complex and has been widely subsumed in a broad concept of the latter. The species is reported to range from se. New York and e. Pennsylvania to east-central North Carolina. Although it is poorly known in Virginia, we follow Ballard et al. (2023, Jour. Torrey Bot. Soc. 150(1): 3-266) in recognizing V. stoneana as a separate species. It differs from V. palmata in pubescence characters and leaf morphology, as well as an apparently discrete distribution along the eastern Piedmont and a putative association with richer, often more mesophytic forests than similar species. Although vouchered records are few, herbarium specimens and iNaturalist reports verified by Ballard suggest that the species is widespread in the eastern half of the Piedmont. Additionally, Viola palmata var. palmata of the Southeastern Piedmont and Coastal Plain is similar, and herbarium specimens need re-evaluation to determine the relative distributions of these taxa in Virginia. At present, it appears that V. palmata var. palmata is confined in Virginia to the Coastal Plain, while V. stoneana is generally restricted to the Piedmont.
- Habitat
- Ballard et al. (2023) describe the habitat as "moist loamy soils of rich mesic forest slopes and bases of slopes" along the Piedmont "Fall Line." Some of the Virginia specimens have been collected or reported on iNaturalist from more dry-mesic and only moderately base-rich soils, and from locations well away from the Fall Line. Obviously, further study of this somewhat elusive taxon is badly needed.
