Looks like a calyx cluster, with a possible modified (mutant) nanner at it's side. Are the 'spikey' appendages somewhat rigid, or super-soft? I get 'em once in a while, but has never resulted in pollen nor seeds. Do you breed your own seeds, or do you purchase 'em?

Can you carefully split-open the banana-looking appendages down it's length, and see what's inside?

I'd look for seeded calyxs on the plant. (yellow 'racing stripe' from base to tip)
If no seeds are forming, and even if those are modified (mutant) nanners, the pollen may not be viable.

How long have they been in flower?
