Hymenoxys hoopesii (formerly Dugaldia hoopesii) is a species of flowering plant in the daisy family known by the common names owl's claws, orange sneezeweed, and yerba del lobo. It is native to the western United States, where it grows in habitats of moderate elevation, such as mountain meadows in the Rocky Mountains, Sierra Nevada, southern Cascades, and other ranges. It has been found from Arizona, New Mexico, and central California north as far as Montana and Oregon.Biota of North America Program 2014 county distribution mapSEINet, Southwestern Biodiversity, Arizona chapterCalflora taxon report, University of California, Hymenoxys hoopesii (A. Gray) Bierner, 1994. Owl’s-claws, orange-sneezeweed H. hoopesii is an erect perennial herb growing up to about 1 meter (40 inches) in height, with smooth-edged leaves up to 30 cm long, oval on the lower stem and lance-shaped toward the top. Blooming from July to September, the inflorescence bears several flower heads on erect peduncles, each lined with a base of hairy, pointed phyllaries. The flower head is up to 7.5 cm wide and has a center of 100–325 tiny disc florets fringed with 14–26 orange or yellow ray florets, each ray up to 2.5 cm long. The fruit is an achene with a pappus of scales.Flora of North America, Hymenoxys hoopesii (A. Gray) Bierner, 1994. Owl’s-claws, orange-sneezeweed The species is toxic to livestock, especially sheep. The pollen also causes an allergenic reaction, hence the common name 'sneezeweed'. The root has been used medicinally to treat rheumatism, upset stomachs, and indigestion in infants.

06Genome at a glanceCCDB
The complete instruction manualHymenoxys hoopesii 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.

09Environmental DNA1 detections
Where the DNA of Hymenoxys hoopesii was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How strong is each trace?
DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.
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.
