Annual or perennial herbs. Leaves alternate, entire or coarsely toothed. Capitula apparently axillary, solitary or in monochasial cymes, sometimes grouped into racemelike synflorescence, sessile or shortly pedunculate, heterogamous and discoid. Involucre small, hemispheric; phyllaries in 1 or 2 series, subequal, herbaceous, margins scarious. Receptacle flat or convex, naked. Marginal florets female, in several rows, fertile; corolla minute, tubular, obscurely 3-lobed, creamy white, pale yellow, green, or purplish. Disk florets few, bisexual; corolla campanulate, 4-lobed, similar in color, glabrous. Anthers obtuse at base. Style branches of disk florets short, truncate. Achenes scarcely compressed, obtusely 3- or 4-ribbed or -angled; corona absent.
