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.
