sred98,
This key is for the eastern U.S. violets but maybe it will help some anyway. Good luck, Tom |

Yes, the AVS key is very helpful.
Also, I find the following web site with its photographs, very helpful, even though some of the Latin has not been updated to latest nomenclature. When the page opens: At the top of the page, in the 'Quick Jump' box, select 'Gallery'. When that page opens, in the box where is asks you to select by name,symbol or group select 'Genus' and then type in Viola, then click on 'Display Results'. You get a typed list. Just above it is the option to chose a chart of photo thumbnails.
I hope you find this useful.
