Leaves basal and cauline; usually sessile; basal blades oblanceolate to lance-linear, margins usually runcinate-pinnate to dentate, rarely entire; cauline similar, smaller, margins dentate or entire. Heads mostly in glomerules (axillary and nearly sessile), some borne singly (on ± elongate peduncles). Peduncles (dimorphic: most 0–2 mm, some 12–85+ mm): the longer often slightly inflated distally, not bracteate. Calyculi 0 (or interpreted as outer phyllaries). Involucres ± cylindric, 3–5+ mm diam. Phyllaries 10–15+ in 2+ series, lance-ovate to lanceolate or linear, unequal, margins little, if at all, scarious, apices obtuse to acute. Receptacles flat, pitted, ± hispid, usually epaleate. Florets 8–25+; corollas usually blue [purple], sometimes pink or white. Cypselae brownish, ± prismatic (3–5-angled), not beaked, faces smooth, glabrous; pappi persistent, coroniform (of 40–60+, whitish, subequal, erose scales in 1–2 series). x = 9.
