Is Caulavola an intergeneric and if so which genuses are the parents?
Unfortunately the page on the RHS website that I used to get this info from has been removed since they restructured the site. I also can't find the answer by googling.
So... is Caulavola an intergeneric and if so which genuses are the parents?
If it's not an intergeneric, then which genuses is it related to?
I'm trying to get my head arround the relationship of various genuses and I've not been able to place this one.
