Annual to tree
Leaves basal or cauline, alternate to whorled, simple to compound
Inflorescence: 1° inflorescence a head, each resembling a flower, 1–many, generally arrayed in cymes, generally subtended by ± calyx-like involucre; flowers 1–many per head
Flowers bisexual, unisexual, or sterile, ± small, of several types; calyx 0 or modified into pappus of bristles, scales, or awns, which is generally persistent in fruit; corolla radial or bilateral (rarely 0), lobes generally (0)4–5; stamens 4–5, anthers generally fused into cylinder around style, often appendaged at tips, bases, or both, filaments generally free, generally attached to corolla near throat; pistil 1, ovary inferior, 1-chambered, 1-seeded, style 1, branches 2, generally hair-tufted at tip, stigmas 2, generally on inside of style branches
Fruit: achene, cylindric to ovoid, generally deciduous with pappus attached
Genera in family: ± 1300 genera, 21,000 species (largest family of dicots): worldwide. Largest family in CA. Also see tribal key to CA genera: Strother 1997 Madroño 44(1):1–28. See glossary p. 25 for illustrations of general family characteristics.



Annual, perennial herb, shrubs
Leaves simple, opposite or alternate
Inflorescence: heads radiate or discoid, solitary or in few–many-headed cymes; phyllaries in 2–6 equal to very unequal series, free; receptacle flat to conic, chaffy; chaff scales entire, folded around ovaries
Ray flowers fertile or sterile; corollas yellow to white
Disk flowers many; corollas yellow to orange; style branches acute to acuminate
Fruit: ray achenes triangular or 0; disk achenes flattened, wing-margined, obovate; pappus 0 or of 2 awns
