[Taxacom] Viola bicolor status

[Kenneth Kinman]

Hi John,          Yockteng et al., 2003 (page 154) say that Section Melanium contains one
species that "is disjunct and probably native in
North America (Clausen et al. 1964)."  Unfortunately, bicolor doesn't seem to be included in that molecular study.         It seems like everyone who believes V. bicolor is native to North America does so based mainly on the work of Clausen. but they continue to use the phrase "probably native".  Anyway, the weblink below will take you to the paper by Yockteng et al., 2003:

> This species has historically been known as Viola rafinesquii and considered an exotic species in North America, but recently changed names and status to a native.  As at TNCer, my ability to track down the rational for this change has been elusive (we're cheap as have access to low end literature resources!).  Can anyone help me track down the basis of that change?
