Ray florets are one of the narrow flowers, resembling single petals, that surround the central disk (disk florets) in the capitulum, or flower cluster of- a plant of the composite family (Asteraceae or Compositae), such as the daisy or sunflower. These have bilaterally symmetric (zygomorphic) tubular corollas. Ray florets are usually pistillate or sterile and have three or fewer teeth on the extended portion of the corolla (i.e. the ray).
