They were much smaller. Red Daccas (the red banana) are commercially available in some countries like Australia, but probably because they grow them.

I think commercial development of a "Cavendish Replacement" ought to be a real plan to diversify the banana business. Monocultures are inherently troublesome. If we could lose this meme in the Europe and North America that there is such a thing as "a banana" and start eating different varieties, I think that would be great.
