Family Compositae
The largest family of flowering plants , the Compositae (Asteraceae), comprising about 1,100 genera and more than 20,000 species and characterized by many small flowers arranged in a head looking like a single flower and subtended by an involucre of bracts. A head may consist of both ray flowers and disk flowers, as in the sunflower, of disk flowers only, as in the burdock, or of ray flowers only, as in the dandelion.

, biennials, perennials
,] subshrubs
, or shrubs (often aromatic
), mostly 20-80 cm; taprooted. Stems usually 1, usually erect
