Heads in paniculiform to thyrsiform arrays. Peduncles not inflated distally, sometimes bracteolate. Calyculi of 2–4 (often spreading to patent), ± deltate to lanceolate bractlets in 1 series. Involucres narrowly cylindric, 1–2+ mm diam. Phyllaries (4–)5 in 1(–2) series (reflexed in fruit), linear, equal, margins little, if at all, scarious, apices rounded.
