Hi !

I think that question had been already posted by the past. I found an old post about it :o)

All the best
Thierry.

Here is a link that might be useful: post by the past

A similar question was asked yes, however my question was about a web listing for all the species. Also that question was not answered fully, my question was more specific.
However I have found a site that does list known species and chromosome counts.Just follow the link and type in 'Viola' and your email, they'll send you a rtf file of the counts.

"All the best" to you too Thierry

Here is a link that might be useful: Chromosome listings

Well, I did and here is what I've just recieved:
