Hieracium or hawkweeds, like others in the family Asteraceae, have mostly yellow, tightly packed flower-heads of numerous small flowers but, unlike daisies and sunflowers in the same family, they have not two kinds of florets but only strap-shaped (spatulate) florets, each one of which is a complete flower in itself, not lacking stamens and joined to the stem by leafy bracts. As in other members of the tribe Cichorieae, each ray corolla is tipped by 3 to 5 teeth.
