These are trees, shrubs, subshrubs, and perennial herbs. They have alternately arranged leaves and some have basal rosettes. The inflorescence is a solitary flower head or a few or many. Some only have disc florets, and some also have ray florets. The heads are small, with just a few florets, or large, with hundreds. They are usually white to orange, but some species have pink or purple florets. The disc florets are tubular with deep lobes at the tips.
