In the daisy family, the flower heads are made up of many small flowers called florets, and are either *homogamous *or *heterogamous*. Heterogamous heads are made up of two types of florets, ray florets near the edge and disk florets in the center. Homogamous heads are made up of just one type of floret, either all ray florets or all disk florets.
