Leaves cauline; opposite; petiolate or sessile; blades (1-nerved or 3-nerved) lanceolate to lance-linear, bases cuneate, margins serrate to subentire, faces sparsely scabrellous. Heads radiate, in loose, corymbiform arrays or borne singly. Involucres hemispheric, 3–5 mm diam. Phyllaries persistent, 8–12+ in 2–3 series (lanceolate to linear, subequal, thin-herbaceous, spreading in fruit). Receptacles flat to convex, paleate (paleae linear to filiform, not conduplicate, falling with fruits). Ray-florets 20–40 (in 2–3+ series), pistillate, fertile; corollas white or whitish. Disc-florets 15–30+, bisexual, fertile; corollas white or whitish, tubes much shorter than ampliate, cylindric throats, lobes 4–5, ± deltate.
