When talking about bananas, you are bound to use the scientific names, because there are few common names for them. Well, I have seen many ways to write the names, so I just wanted to show how scientific names are supposed to be written.
So, Musa, or Musella, or Ensete or whatever, the first name, family name is to be written with big letter. Then the name after that, is to be written with small letter. Then there is the variation thing name, like 'African Red', shall have like ('), and not (").
Some examples: Musa ornata 'Royal Purple', Musa ssp. 'Helen's Hybrid', Ensete ventricosum 'Maurelii'
Not so extremely important, but it looks better and is better to have it right..
