Pericome caudata is a species of flowering plant in the aster family known by the common name mountain tail-leaf. It is native to the southwestern United States as far east as Colorado, Oklahoma, and Texas, as well as northern Mexico, where it grows in rocky habitat, often in hills and mountains, and sometimes in disturbed areas. It is a large, branching, leafy perennial herb or subshrub approaching 2 meters in maximum height. It is glandular, resinous, sparsely hairy, and aromatic. The leaves are somewhat triangular, sometimes with a few large teeth or sharp lobes, the blade measuring up to 12 centimeters long and borne on a petiole. The leaf size and shape is variable across the species' range.Flora of North America The inflorescence is a cluster of many flower heads each under a centimeter wide and filled with golden yellow disc florets. The Navajo used this plant for a variety of medicinal and ceremonial purposes.Ethnobotany

Compounds documented for Pericome caudata across natural-product and food-composition databases — not just the ~150 nutrients on a classic label ("nutritional dark matter").
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 Pericome caudata has left across the world's sequence archives.

The complete instruction manualPericome caudata 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.

Where the DNA of Pericome caudata 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.
