That is a nanner cluster.

My LST has been pumping out the occasional nanner here and there. Every time I pluck them out a new cluster forms in that same flower. So I started plucking out that entire flower.

BTW, if you pop a nanner it will have pollen in it. However while still green it seems to not. I popped a couple here and there a week ago. Looks like each one popped, pollinated the flower I pulled it from.
