Aster (Daisy)

A typical Asteraceae flower head (here Bidens torta) showing the individual flowers

Flowers of a sunflower with different forms and phases (sterile ray flowers, disc flowers in female, male and unopened phases)

Plants in the Aster family typically have one or both of two kinds of florets. The outer perimeter of a flower head like that of a sunflower is composed of florets possessing a long strap-like petal, termed a ligule; these are the ray florets. The inner portion of the flower head (or disc) is composed of small flowers with tubular corollas; these are the disc florets. The composition of asteraceous inflorescences varies from all ray flowers (like dandelions, genus Taraxacum) to all disc flowers (like pineapple weeds).
