(Above) How weird is that?! The filaments curl back onto the petals and the anthers shed pollen at the same time that the stigma is receptive in some species of tuberous perennial Claytonia!
(Above) In others, the filaments begin to curl back when the anthers start shedding pollen, with the stigma become receptive shortly thereafter. Excellent!
(Below) In this species, the filaments curl back and the stigma becomes receptive after most of the pollen has seemingly been released. Gnarlatron!
(Below) And still in others it seems like the filaments don’t reflex much toward the petals at all. Whoa!
But what does it all mean?! That is a good question… I’ll have to get back to you on that one.

Very cool!! Could it be that there are different degrees of protandry? And it seem so cool that the anthers tend to curl back towards the yellow patches!! Pollen mimicry in the patches perhaps with the curling back resulting in touching the visitors that get fooled? All so cool. Thanks for sharing Tommy!
I think there are definitely different degrees of protandry, but I’ve never thought about how it relates to guides on the petal bases. Nice observation, Ricardo!
