quite strange situation, I call it a tree, and in fact this plant - grass )
To clarify for myself the situation, I asked help from Google
i ask him - banana - tree or grass?
he said that banana is a perennial herb, this plant, though called a 'banana tree' in popular use, but in fact it is a herbaceous plant, not a tree.
I was lucky enough to take a photo of the felled trunk - he really does not contain true woody tissue.
