I can't seem to find credible articles coming from Internationally Accredited Scientific Body, or Authoritative Scientific organizations declaring what the official scientific naming of different banana cultivars should be. Would appreciate it if there was a meeting, conference, consensus and proclamation stating such standardization or naming convention, at least for bananas.
Most wild bananas are edible, if you are not limited to the fruits. The piths are good to use as vegetable fiber. Other wild banana fruits can be eaten if cooked, as they are very astringent when eaten fresh. You can look at various PDF articles in www.inibap.org
the link which I was the first to share in this forum a long time ago.
