Re: Did Ty Ty send me the wrong banana?
I agree that the leaf shape looks like Dwarf Namwah, but it would be very unusual for that variety to have the red blotches on the leaf that this plant has. The leaf shape certainly suggests some dwarf type, but on small plants like this, leaf shape can be misleading. In short, I don't know. And I wouldn't limit your choices to the varieties they claim they have.
Post a picture of the petiole (leaf canal), that might help narrow things down.
