I googled it and the first several listings looked like they were perhaps in Swedish, which I don't speak, but one said it was a mini cane (actually I think it said angel wing) but there was a reference to a post on the Yahoo begonia forum, which I couldn't find, that said Greg Sytch of Florida hybridized it. So I guess it's a valid name! He does good work--I'll have to keep an eye open for it!
