It's a AAA banana, one with 3 copies of the Acuminata genome-that's as much ans anyone can tell from the pictures. The AAA most commonly encountered is Dwarf Cavendish.

I have others that dwarf cavendsih that don't bare that color of trunk.
The nanner on the far left is the mom of the 2 little ones,the mother top out about 15 ft to the top of the leaves.
I had one cavendish flower and fuit over last winter,nanners ripen about May,and were very Delicious.
