Phyllaries 3–8 in 1 series (± lance-linear, herbaceous, each fully enveloping a ray ovary, abaxially hirsute or villous and sparsely glandular-pubescent or eglandular). Receptacles flat to convex (setulose), paleate (paleae falling, in 1 series between rays and disc, distinct). Ray florets 3–8, pistillate, fertile; corollas yellow, turning reddish (lobes ± parallel). Disc florets 4–35, bisexual and fertile; corollas yellow to reddish, tubes ± equaling narrowly funnelform throats, lobes 5, lance-deltate (anthers ± dark purple; styles glabrous proximal to branches).
