Pappus (flower structure)

In a composite flower, Pappus is the part of individual disk and ray flowers that surrounds the base, in the same manner as the calyx does in a non-compound flower. The pappus may be like bristles or tiny hairs, teeth, or scales, and is usually too small to see without magnification. The name derives from the Ancient Greek word pappos, Latin pappus, meaning "old man", so used for a plant (assumed to be an Erigeron species) having bristles and also for the woolly, hairy seed of certain plants.
