Receptacles conic, muricate, glabrous. Ray-florets 6–16; laminae linear to oblong, 5–18 mm. Anther appendages deltate to sublanceolate. Cypselae black to gray or silver-gray, linear to narrowly clavate, to 4 mm, glabrous or hairy; pappi 0, or of 1–7 translucent (rarely opaque), brown (rarely white), linear to subulate, aristate scales.
