Description Erect or sprawling, short-lived herbs. Leaves opposite, simple, entire or toothed, mostly pubescent with verrucose hairs arising from expanded bases.

Heads radiate; involucral bracts imbricate in ca. 2 similar or irregular series, ovate to lanceolate, apically acute and mucronulate, herbaceous or somewhat indurate below; receptacle flat or somewhat convex, muricate; paleas slender, bristlelike, apically barbed; ray florets in 2-3 series, fertile, the corolla white or yellow, the tube short, puberulent, a staminode sometimes present; disc florets more numerous than the ray florets, fertile, 4-merous, the corolla campanulate, angled, the lobes ciliate, the anthers sagittate, the appendages ovate, the style branches acute. Achene dorsiventrally flattened, the sharp angles extended near the base, the pericarp tuberculate, brown; pappus of thick scales partially united in a cone.
Habit herbs
Note Although many names have been published in the genus, there are apparently only two species, the one described here and E. bellidioides (Spreng.) Blake from Uruguay. Eclipta alba is a near-cosmopolitan weed. Eclipta is distinguished by the conelike pappus, bristlelike paleas, and sagittate anthers.
