Disc florets: An early stage disc floret is a vertical tube consisting of five fused anthers surrounding the style and producing pollen on the inside of the tube. | |

As the floret matures towards the edge of the disc the two-branched stigma emerges from the top of the anther tube and in the process collects pollen on the brushes under each branch. The pollen does not germinate on the stigma because of self-incompatibility, but its location on the stigma facilitates collection by insect pollinators. | |
