Good morning Dr. Hakkinen,
The problems you state are known to us. That is the reason for the question. What morphological differences are there between the subspecies, such as petioles, petiole wings, petiole wing remanence, pseudostem thickness or color, or lack of, waxyness of petioles, arrangement of flowers, bunch sizes and arrangements? The problems you've stated is why many of us are trying to identify what we do have.
Thank you for your attention to this matter, May you have Good weather and research, and may your findings or conclusions be accurate.
