(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!
