|discussion=<p>Genera 100+, species 1700+ (26 genera, 99 species in the flora).</p><!--
--><p>Centers of concentration for anthemids are in the Mediterranean regions of Europe and Africa, in central Asia, and in southern Africa.</p><!--
--><p>Studies by L. E. Watson et al. (2000) and syntheses by K. Bremer and C. J. Humphries (1993) and by C. Oberprieler et al. (unpubl.) have resulted in changes in circumscriptions for some genera and in better understandings of relationships among genera of anthemids.</p><!--
--><p>From 1753 until near the end of the 20th century, the mums and florists’ chrysanthemums of horticulture, along with marguerites, Paris daisies, Shasta daisies, and others, were included by most botanists in Chrysanthemum. Then, traditional Chrysanthemum came to be dismembered (see, e.g., K. Bremer and C. J. Humphries 1993) and the mums, florists’ chrysanthemums, and their closest relatives came to be treated botanically in the genus Dendranthema. A great hue and cry ensued from horticulturalists, especially in Europe. The upshot was that a proposal to typify Chrysanthemum on C. indicum (florists’ chrysanthemum) succeeded, and that generic name is once again applied to the mums and florists’ chrysanthemums of horticulture, none of which is known to be well established in the flora area. Here, the marguerites and Paris daisies are treated in Argyranthemum, Shasta daisies in Leucanthemum, and corn chrysanthemums and crown daisies in Glebionis.</p><!--
--><p>Some cultivated members of Anthemideae have been reported as ephemeral or ± persistent escapes in the flora area. Some of those are documented in generic treatments below; others include florists’ chrysanthemum (Chrysanthemum indicum, which may be encountered as abandoned plantings almost anywhere in the flora area) and Shasta daisy (reported for Michigan as Chrysanthemum ×superbum J. K. Ingram by E. G. Voss 1972–1996, vol. 3; see treatment of Leucanthemum).</p><!--
--><p>Centipeda minima (Linnaeus) A. Braun & Ascherson has been recorded from Massachusetts and Pennsylvania as non-persistent introductions. The plants are somewhat succulent, gland-dotted annuals with stems decumbent to procumbent, leaves oblanceolate to cuneate, mostly 5–15 mm, usually lobed or toothed distally, heads disciform, involucres hemispheric or broader (2–3+ mm diam.), phyllaries in 2–4 series, pistillate florets in 2–8 series, bisexual florets 10(–30), corollas yellow, 4-lobed, and cypselae obovoid, 1–1.5 mm, epappose. Traditionally, Centipeda has been included in Anthemideae; in more recent studies, it has been placed in Astereae (e.g., E. V. Boyko 2003; G. L. Nesom 2000) or in Centipedinae within Athroismeae (J. L. Panero 2005).</p>
