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.
, 5-250 cm. Stems erect
. Leaves mostly cauline (at flowering) proximal
opposite (often in rosettes), distal alternate; sessile; blades
lanceolate or oblong-linear to linear
usually entire, sometimes toothed
, usually glandular-pubescent
as well. Heads usually radiate

). Receptacles flat to convex

). Ray florets 0 (sometimes in M. glomerata), or 1-22, pistillate
