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.
