01Narrative

Hymenoxys ambigens is a species of flowering plant in the daisy family known by the common name Pinaleño Mountains rubberweed. It is native to the states of Arizona and New Mexico in the southwestern United States.Biota of North America Program 2014 distribution mapSEINet, Southwestern Biodiversity, Arizona chapter description, photos, distribution map Hymenoxys ambigens is a perennial herb up to 150 cm (5 feet) tall. Leaves have very narrow lobes resembling branching threads. One plant can produce an array of 25–400 small yellow flower heads, each head with 3-5 ray flowers and 6–15 disc flowers.Flora of North America, Hymenoxys ambigens (S. F. Blake) Bierner, 1994.

05DNA & barcoding1 eDNA hits

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Hymenoxys ambigens has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Hymenoxys ambigens 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 ambigens 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.
