01Narrative
Hymenoxys cooperi is a species of flowering plant in the daisy family known by the common name Cooper's rubberweed. It is native to the southwestern United States and Great Basin, where it grows in rocky soils in arid regions from southern California to New Mexico, north as far as Idaho and Oregon.Biota of North America Program 2014 distribution mapCalflora taxon report, University of California, Hymenoxys cooperi (A. Gray) Cockerell, Cooper goldflower, Cooper's goldflower, Cooper's rubberweedSEINet, Southwestern Biodiversity, Arizona chapter description, photos, distribution map Hymenoxys cooperi is a biennial or perennial herb with a branching stem growing erect to heights between 15 and 90 centimeters (6-36 inches or 0.5-3.0 feet). It produces narrow, pointed leaves with two lateral lobes that form a trident shape. The foliage and stem are glandular and waxy, usually with a thin coat of light-colored hairs. The daisy-like flower head is a cup of fused phyllaries with 30–150 tiny yellow-orange disc florets surrounded by 9–14 bright yellow ray florets, each ray about a centimeter (0.4 inches) long.Flora of North America, Hymenoxys cooperi (A. Gray) Cockerell, 1904. Cooper’s rubberweed or bitterweed

06Genome at a glanceCCDB
The complete instruction manualHymenoxys cooperi 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.
