Hi Guys,
This is Phil at Trebrown Nurseries.
I just wanted to point out the fact that I don't claim to be any form of banana expert at all. My expertise lies in palms and cycads.
I also want to point out that all of the Burmese banana seeds that I had in last year... the dark form of Musa cheesmanii, Musa aurantiaca, Musa nagensium (true form), and the exceptionally large form of Musa velutina were all identified by Markku Hakkinen in Finland from pictures and seeds sent to him from myself. He assured me that all his identifications were 100% correct. I have also sent him the Musa nagensium X seeds that we were selling 3 years ago and that I know many people are still selling now. You don't want to question Markku too much on these subjects, he very soon looses patience with you. Therefore I never got a definitive answer as to what the Musa nagensium X seeds were. He just said they are not Musa nagensium.
I, however do tend to agree with some of the comments above in that they are very similar, if not the same as Musa cheesmanii.
Hope this clears things up a little.
Regards,
Phil
