the first pic is the only concern... in middle of flower looks like a potential sac...
could also be the photo playing a trick.
other pictures are clearly female...
the preflower in 4th picture has a white hair-like projection -- that is female anatomy.
that first pic could just be a sugar leaf doubled over or something?
if you take a closer look it is a sac w ith something in it, that's bad. that would be a male organ.
like i said... can't be certain from that picture.. go takea peak.. is that thing in center just a leaf or is it a bit bulbous and likely containing something? you have time before the mature and open up (nanners inside) ... at which point your entire area could be pollinated from 1 pollen sac.
individual nanners soemtimes form -- lile yellow banana-looking things that are also found inside a pollent sac (anther?). anyway, these are less dangerous and produce much less pollen on their own. pluck'em carefully unless it's just rampant all over and not worth the time. they are impotent when green, but as they mature and become potentially viable they turn yellow. (some nanners are impotent / sacs are dangerously full of pollen)
