(glomerules of heads usually subtended by leaves or ± foliaceous bracts). <b>Phyllaries</b> persistent, 4–5[–8+] in ± 1 series (linear-attenuate, proximally connate, often 1 or more with 1[–3+] glands in abaxial face). <b>Receptacles</b> convex (often hirtellous), rarely paleate (paleae linear). <b>Ray</b> florets 0. <b>Disc</b> florets 1(–2)[–8], bisexual, fertile; corollas yellow [white, pink, or red], tubes shorter than cylindric to campanulate throats, lobes 5, lance-linear to lance-ovate [rounded-deltate] (often hairy). <b>Cypselae</b> (brown to black) narrowly cylindric to obovoid or clavate (faces glabrous or pilosulous, minutely grooved); pappi ± coroniform. <b>x</b> = 17.</span><!--
