Perennials, (1–)2–8(–12+) dm; often rhizomatous or stoloniferous. Leaves mostly basal or mostly cauline at flowering; sessile or petiolate, petioles ± winged (often clasping at bases); blades mostly elliptic, ovate, or obovate to lanceolate, oblanceolate, or spatulate (rarely orbiculate), bases ± cuneate, margins usually toothed (rarely entire), apices obtuse to acute, abaxial or both faces usually resin-gland-dotted. Heads ± discoid, sessile, not individually bracteate, in clusters of (1–)10–40+ in corymbiform-paniculiform arrays 6–15(–25) cm diam. (each cluster subtended by 2–3 ± deltate bracts). Involucres ± cylindric, 1–3+ mm diam. Phyllaries 8 in 4 decussate pairs, the outer 4 ovate, inner 4 lanceolate, all ± chartaceous, margins entire, tips ± spinose to apiculate, abaxial faces of inner 4 usually dotted distally with resin glands. Florets (1–)4(–5+); corollas white or pink to purple, tubes longer than abruptly funnelform throats, lobes 5, lance-linear, unequal (abaxial sinus deepest). Cypselae ± clavate, sometimes ± flattened, 10-nerved or -ribbed, strigillose to hirsutulous; pappi persistent, of 5(–6), 1-aristate scales (look closely for squamiform, gradually to abruptly tapering base of each arista). x = 11.

Distribution

Mostly warm-temperate, subtropical, and tropical regions worldwide, sometimes as naturalized ruderals.

Discussion

Species 12–15+ (4 in the flora).

Pseudelephantopus spicatus is sometimes treated as a member of Elephantopus.
