Perennial simple or branched herbs. Leaves alternate, chiefly radical or on median part of stem, entire to lobed. Heads discoid, small, few flowered, sessile or pedunculate, in racemes, spikes, or panicles, often pendulous. Involucres narrowly tubular; bracts in many series, imbricate; receptacles glabrous. Florets few, narrowly tubular, reflexed. Anthers with sagittate base, tails long, connate, bearded. Style arms short, flat, rounded to truncate at apex, spreading. Achenes oblanceolate, rather flattened, many-ribbed, apex truncate, base narrowed, glabrous or coarsely pilose. Pappus bristles in one series, plumose, sometimes absent.
About 80 species in eastern Asia and India; four species in Taiwan.
