Hymenopappus filifolius is a species of flowering plant in the daisy family known by the common names fineleaf hymenopappus and Columbia cutleaf. It is native to western North America from west central Canada to northern Mexico. It grows in a number of habitats, often in arid regions. The plant is variable in appearance and there are a great number of varieties of the species. It is a taprooted perennial herb growing as a small clump on the ground to an erect spray of stems up to a meter tall. Almost all of the leaves are located at the base of the plant in a woolly gray-green patch. They are up to 20 centimeters long and are divided into blunt, thready leaflets. They are glandular and thinly hairy to quite woolly, and dark green under the coat of white wool. The stem ends in a branching inflorescence of knob-shaped discoid flower heads. They are filled with golden yellow or white disc florets. There are no ray florets.

There are many varieties, including:

  • H. f. var. eriopodus - a white-flowered variety native from California to Utah
  • H. f. var. filifolius - found mostly in the Pacific Northwest
  • H. f. var. idahoensis - (Idaho hymenopappus) - endemic to Idaho
  • H. f. var. nudipes - (alpine hymenopappus) - known from Utah and Wyoming
  • H. f. var. parvulus - endemic to Colorado

Uses[edit]

The Zuni people apply a poultice of chewed root with lard to swellings. They also drink a warm decoction of the root as an emetic.[1] They also use the root as chewing gum. [2]
