Bushy herb to around 60 centimetres in height, consisting of multiple stems crowned by dense clusters of yellow, button-like heads. Leaves are narrow and linear, reaching 5 cm in length at the base of the plant but usually < 1 cm long near the inflorescence. They may be slightly hairy and silver, expecially near the base, or green and largely hairless. Flowers are smaller and more numerous than for C. apiculatum. Seeds are tiny and carry a crown of hairs, facilitating their dispersal by wind.
