Dear All, I have a few different Dioscoreas. Most of them were raised by seed. I would like to know if anybody knows an expert. I've tried to look for keys but there are only keys for N. American and Chinese species, none for Europe. It is a quite an overlooked genera. And hard to ID. Any help is very wellcome. If somebody would like to do genetical research I can send leaves. Bye, Jan Z5a, Hungary
