Those are just calyxes. I had one herm on me my first grow that still produced extremely potent bud and about 20 plump dark seeds. I popped one of those seeds this run and it grew identical so I'm guessing they're feminized and of high quality. I wasn't running a fan at the time so it was like one nanner at the top busted onto the bud under it and I plucked the rest before they popped. It happened after leaving my flowering light on for a full 24hrs by accident. They literally look like a little cluster of bananas from Donkey Kong Country.
