I got an email from RPS yesterday and they have loads of new species of musa available from Borneo. They are too numerous to list, but
I had to buy some.
I'm not on commision, and I think they are a bit expensive, but check them out.

I bought some musa bauensis and musa monticola, never heard of them, but boy am I excited.
