They are all over, but I uploaded a few photos from one that has opened. Same internal structure, this one just opened to reveal pistils. Do pollen sacs and calyxes have the same internal structure?
I was going to see what sort of chore removing the sacs would be and found this. Shaped the same, only this sac has opened to reveal pistils.
Maybe I should just wait and see what happens? There are no other plants in there to be pollinated.
