Description
"Perennial or annual, erect herbs, stems erect, densely short pubescent, terete to obscurely angled, strict to freely branched. Leaves alternate, serrate, the teeth-callous-thickened, petiolate to sessile. Heads corymbose. Involucres hemispheric to campanulate, many flowered; bracts imbricate, in several series. Flowers all discoid, perfect, very small. Nutlets small, cylindric, 5-ribbed; pappus bristles whitish, capillary, minutely, antrosely barbed, 3-4 mm long." - Radford et al 1964
"Pubescent perennial, 4-11 dm tall, usually strict. Leaves oblong to elliptic-oblong, 3-9 cm long, 1.3-5 cm wide, obtuse to acute, auriculate-clasping sessile. Heads sessile or essentially so in glomerules in compact corymbs, the lateral branches usually overtopping the central. Involucres 3-6 mm long; bracts acute. Corollas pink. Nutlets black, 0.5-1 mm long, densely pubescent." - Radford et al 1964
