Hymenoxys richardsonii, the pingue hymenoxys or pingue rubberweed, is a North American species of plants in the sunflower family. It is widespread across the western United States and western Canada from Arizona, New Mexico, and western Texas north as far as Alberta and Saskatchewan.Biota of North America Program 2014 county distribution map VarietiesFlora of North America, Hymenoxys richardsonii (Hooker) Cockerell, 1904.

06Genome at a glanceCCDB
The complete instruction manualHymenoxys richardsonii 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 richardsonii 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 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.
