Revision as of 20:41, 27 May 2020

Annuals, biennials, or perennials (shrubs in A. californica, subshrubs in A. nesiotica); usually fibrous-rooted, sometimes taprooted, caudices sometimes woody, rhizomes sometimes present. Stems usually not wandlike (wandlike in A. californica, A. nesiotica, A. palmeri). Leaves usually deciduous, rarely persistent, basal (rosettes) and/or cauline (not in fascicles). Heads usually disciform (discoid in A. nesiotica and A. palmeri). Receptacles glabrous (paleate in A. palmeri). Florets: usually peripheral 3–20 pistillate and fertile (0 pistillate in A. nesiotica, A. palmeri); central (or all) 14–70 bisexual and fertile; corollas funnelform.

Distribution

Widespread in Northern Hemisphere, especially North America, Europe, and central and northern Asia, sporadic in South America and northern Africa.

Discussion

Species ca. 220 (27 in the flora).
