Hymenopappus filifolius is a North American species of flowering plant in the daisy family known by the common names fineleaf hymenopappus and Columbia cutleaf. It is native to western and central North America from Alberta and Saskatchewan south as far as Chihuahua and Baja California.Biota of North America Program, 2014 county distribution mapSEINet, Southwestern Biodiversity, Arizona chapter photos, description, distribution map Hymenopappus filifolius 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 (40 inches) 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 (8 inches) 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.Flora of North America, Hymenopappus filifolius Hooker, 1833. There are many varieties, including: Hymenopappus filifolius var. eriopodus – a white-flowered variety native from California, Nevada, Utah Hymenopappus filifolius var. filifolius – Idaho, Oregon, Washington Hymenopappus filifolius var. idahoensis – Idaho Hymenopappus filifolius var. lugens – Arizona, California, Nevada, Utah, New Mexico, Baja California Hymenopappus filifolius var. luteus – Utah, Wyoming, Colorado Hymenopappus filifolius var. megacephalus – California, Nevada, Utah, Arizona, Colorado Hymenopappus filifolius var. nanus – Arizona, California, Nevada, Utah Hymenopappus filifolius var. nudipes – Utah, Wyoming Hymenopappus filifolius var. parvulus – Colorado Hymenopappus filifolius var. pauciflorus – Utah, Arizona, Colorado Hymenopappus filifolius var. polycephalus – Alberta, Saskatchewan, Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota, Wyoming Hymenopappus filifolius var. tomentosus – Utah

The complete instruction manualHymenopappus filifolius carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
