Outer florets filiform, female, minutely 3-lobed, fewer than inner florets; inner florets bisexual, 4-lobed, stamens 4, anthers tailed, style branches truncate. Cypselas minutely puberulous with short, globose, mucilage-producing hairs; pappus in bisexual florets of 2–4, free, persistent, shortly plumose bristles equal to or exceeding the florets, in female florets reduced and sometimes a jagged cup.
