Re: Unknown Cavendish
From what I've read, the only reliable way to distinguish Cavendish from Gros Michel varieties is the color of the female flowers. In short, you probably can't figure it out from looking at the suckers.
According to Kepler and Rust, Gros Michel female flowers have two red-brown stripes on the upper petal ("compound tepal"), whereas Cavendish lack these stripes. Also, the stigma is brown in Gros Michel and yellow in Cavendish; and the style is white in Gros Michel and bright pink in Cavendish.
