Flowering of any disc floret in all members of aster family is a curious process. Stamens fuse edge-to-edge into a vertical cylinder with a central cavity, their anthers releasing pollen into it before the flower fully opens. Then the hairy immature style grows upward through the stamen tube, its hairs pushing the pollen up and out. As a result, pollen is found on the style (!) instead of stamens, as seen here. After clearing the anther tube and delivering the pollen, each style is going to split into two receptive stigmatic branches ready to catch cross-pollen brought by insects. Photo 3 of 4
