at the base. Stigmas exserted, obtuse, glabrous, often, by abortion, unequal, acute, or one altogether abortive. Achaenia terete, villous, erostrate. Pappus 1 series, seta? elegantly plumose. — Herbaceous perennials; stems erect, simple. Involucre cylindrical, scales lanceolate, acuminated, imbricate. Receptacle naked. Flowers purple.
