Genus Information: 11 species in Hymenopappus throughout the United States and Canada, mostly in western half, central and southern United States, in Canada in Saskatchewan and Alberta, and in Northern Mexico; 6 species in Arizona, 13 varieties in Hymenopappus filifolius; 6 varieties of Hymenopappus filifolius in Arizona.

Comments: Hymenopappus filifolius or Fineleaf Hymenopappus occurs in 13 varieties throughout much of North America, Arizona has 6 varieties in various habitats around the state. As a result, there is much (often subtle) variation in plants from one location to another and they may be difficult to identify individually to specific variety. However, most varieties seem to have enough similar characteristics that they can be easily recognizable to species.

Several ethno-botanical uses have been identified for Fineleaf Hymenopappus including its use as a dermatological aid, emetic and made into bread and cake. For and a complete species account for this species visit the on-line site Native American Ethnobotany, University of Michigan, Dearborn.
