Leaves usually alternate, sometimes opposite or concentrated at the base, usally dissected, dentate, serrate, lobed, or 1-3-pinnatifid to pinnatisect, rarely entire. Heads solitary or in open to dense corymbs, panicles, or racemes, or in clusters, often pedunculate, rarely sessile, heterogamous and radiate or disciform or homogamous and discoid; nvolucres from hemispherical to obconic, cylindrical, or urceolate; phyllaries in 2-7 rows, imbricate, almost always with scarious margins and tips, sometimes with 1-several resin canals; receptacles flat, curved, hemispherical, or conical, glabrous or hairy, with or without bracts subtending the florets; receptacular bracts persistent or caducous, sometimes with a cenral resin canal. Marginal florets sometimes with limbs, pistillate and fertile, or sterile or neuter; limbs ,if present, white with yellow bases over yellow, rarely blue-violet, pinkish or reddish; outer disk florets, un disciform heads, in 1-several rows, pistillate, usually fertile corollas tubular, with 0-5 lobes, usually yellow, rather absent; central disc florets bisexual or functionally male; corollas tubular or funnel-shaped, usually yellow, rarely whitish or reddish, with 3-6 lobes, rarely with central resin sacs; stamens alternating with the corolla lobes, filaments with a cykindrical collar of cells with thickened walls, anthers usually with rounded or shortly tailed based, and ovate, triangular, ro subulate apical appendages; styles with slender or bulbous bases, usually on a cup-shaped nectar-secreting stylopodium, style branches usually free, sometimes fused in functionally staminate florets, adaxial surfaces usually with 2 parallel papillate stigmatic areas. Achenes variusly shaped, 3+--angled in cross-secion, sometimes flattened. Anthemideae is a tribe of 100+ genera and 1700+ species. It has its greatest concentration in the Old World, particularly the Mediterranean region, Europe, Africa and Central Asia. Sources. Barkely, T.M., L.Brouillet, & J.L. Strother. (2006).
