Two sticky monkey flowers, one with an open stigma, one with closed. The stigma closes on touch; if the plant has not been pollinated, it reopens. Thus, a closed stigma indicates a pollinated flower. The stigmas are the white structures at the center of these sticky monkeyflowers (Mimulus aurianticus var. aurianticus). And what is peeking out of the left one? Road c, 7:59 am. iPhone photo.
