These photos have been circulating on the internet for a long time, and honestly, I don't even know if they're real or not. I've never seen this type of fruit in real life. Fruits of Musa ingens are not small, since it's a very big plant, but not that big, and bearing seeds. See pic.

That said, it really is the best for banana flower salad!

This one does not belong to Musa acuimnata. It's a Pisang Awak type, whose origin is hybrid between M. acuminata and M. balbisiana.

Musa velutina. Not ornata.

Although the plant is correct, these are absolutely not the fruits of Musa ingens. It's a wild type with seedy fruits.

This one is Musa velutina. Not zebrina nor sikkimensis.

Musa velutina, not ornata.

The problem being, here, that M. balbisiana is not an ancestor of Cavendish banana...
