Shrubs, 100-200 cm; probably taprooted. Stems straggly (± fleshy), branched, tomentose to glabrate. Leaves cauline (tufted at ends of branches); petiolate; blades obovate to oblong-obovate, margins irregularly sinuate or lobulate. Heads in paniculiform arrays (at ends of branches). Peduncles not inflated, bracteolate (usually stipitate-glandular). Calyculi of 7-10, unequal, triangular to ovate bractlets (lengths to ¹/2 phyllaries). Involucres cylindric, 3-5+ mm diam. Phyllaries 8-9 in ± 2 series, lanceolate to linear, margins narrowly scarious, apices obtuse to acute (often sparsely arachnose), faces glabrous or sparsely glandular-puberulent. Receptacles ± flat, pitted, glabrous, epaleate. Florets 9-12; corollas rosy to purplish. Cypselae gray-brown, cylindric, apices truncate (not beaked), faces 5, equal, each with 1-2, narrow, longitudinal lines or shallow grooves, otherwise smooth, glabrous; pappi falling, of 25-35 distinct, white, antrorsely barbellate bristles in 1 series. x = 8?
