[Taxacom] Viola bicolor status

[David Werier]

Hi John,

A couple papers in Rhodora, which you should be able to access via BHL 
are of interest.

These include the Clausen et al. paper: Clausen, J., R. B. Channell, and 
U. Nur. 1964. Viola rafinesquii, the only Melanium violet native to 
North America. Rhodora 66:32–46.
And a slightly older one: Shinners, L. H. 1961. Viola rafinesquii : 
nomenclature and native status. Rhodora 63:327–335.

We have a couple of populations in New York that grow in isolated rocky 
summit communities at the very northeastern edge of their range. I treat 
them as native.

Best,
David

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:

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?
