The leaves are small and linear on the lower stem, and reduced to scale-like growths on the upper branches. Flower heads occur near the ends of the branches. Each has a cylindrical base wrapped in one layer of phyllaries. The head contains 3 to 5 ray florets, each with an elongated tube and a pale to bright pink ligule. The fruit is an achene tipped with a cluster of pappus bristles which are not plumelike as are those of the Stephanomeria species with which this plant was once classified.
