Dear members, Uli asked:

For tuberous Begonias....... yes there are people out there who like them,

but

I am interested in SPECIES tuberous Begonias. I know there are some very
beautiful ones but impossible to come by..

The American Begonia Society http://www.begonias.org/
has a seed exchange, and I believe a forum where questions may be asked.
There are also URLs, though probably to US oriented sites. Presumably
this would be a starting point. I'm interested, but not motivated to take
on more right now.
