There's no mention of Banana Squash having a green end in it's description.

Nor can I find any which have a green end other than a very occasional one with a hint of green at the blossom end. If the right side was the stem end, and if it was a Banana Squash then I would expect to find some photos with green at the stem end, I can't find any.
