Check the description of my fuzzy violet under missa's post "where to get different violets at reasonable price". I know you said yours wasn't hairy, but mine is more or less hairy under different circumstances.
I've got a picture that I'll try to post this week - take a look and see if it could be the same as yours. If so, there's two of us looking for an ID!

Arcadia -

The book is "Wild Violets of North America", 1942, by Viola Brainerd Baird. There were only about 1000 copies printed, so don't expect to trip over copies that easily.

We really need a piccy to identify your violet...

Meanwhile, try the key at http://www.americanvioletsociety.org/Violet_Keys/Web_Based_Dichotomous_Key.htm. It is primarily for Pennsylvania, but many of the species occur in Virginia, too.

The checklist at http://www.americanvioletsociety.org/Violets_In_America/Botanical_Names.htm
may also be of some help, but note that it contains quite a lot of spelling errors in species names.

But try the link below, too (it seems strangely slow at the moment, though). Here you will be able to determine which species of violet grow wild in Virginia, and get some details about them, including some photos.
