fruit pappus (Q1531)
A set of one or more awns (aristae, bristles, setae) or scales at the summit of an inferior ovary just beneath or outside the free portion of the corolla; persisting in the fruit (cypsela) and often aiding wind or animal dispersal; in Asteraceae (Compositae). Considered by some to be an evolutionarily modified upper calyx portion, the lower portion having been incorporated into the floral tube casing adnate to the ovary wall; considered by others to be an outgrowth from the ovary wall.
