Asteraceae [Compositae]: Annual, biennial or perennial herbs or sometimes shrubs, tissues lactiferous or not. Leaves alternate or sometimes opposite, exstipulate (rarely stipuloid), entire, toothed, lobed or variously dissected. Individual flowers usually numerous (rarely only 1), sessile and aggregated into a capitulum surrounded by a protective involucre pf 1-many series of phyllaries (involucral bracts), rarely fused; capitula sometimes aggregated into a secondary capitulum like head (pseudocephalium). Receptacle naked or bearing paleae (scales), long hairs or bristles. Flowers (florets) epigynous, either all hermaphrodite and protandrous, or female, male (at least functionally so), or neuter (sterile). Calyx represented on apex of ovary by a pappus (enlarging in fruit) of hairs, bristles, scales or awns, or by a ± continuous corona (crown); pappus sometimes completely absent. Corolla gamopetalous, tubular (infundibular, or narrowly cylindrical below and campanulate above), filiform, ligulate or rarely bilabiate, usually 3 or 5 toothed; rarely absent. Stamens (4-)5, epipetalous, filaments usually free; anthers laterally united into a cylinder round the style (i.e. syngenesious), rarely free, dehiscence introrse. Ovary inferior, 1 celled, with 1 basal anatropous ovule; style usually divided above into 2 branches, the styles of the disc flowers often bearing collecting (brush) hairs that sweep the pollen from the anther cylinder. Fruit an achene (cypsela), usually bearing a persistent or deciduous pappus that is sessile or borne on a beak (rostrum).
