Eupatorium pilosum, common name rough boneset, is a rare North American species of plant in the family Asteraceae. It is native to the eastern and south-central United States, found in every coastal state from Massachusetts to Texas, and as far inland as Kentucky.Biota of North America Program, 2014 county distribution map Eupatorium pilosum is a perennial herb sometimes over 100 cm (40 inches) tall, spreading by means of underground rhizomes. The plant produces large displays of large numbers of tiny flower heads, each with 5 white disc florets but no ray florets.

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 Eupatorium pilosum has left across the world's sequence archives.

The complete instruction manualEupatorium pilosum 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 DNA2 detections
Where the DNA of Eupatorium pilosum 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.
