Eupatorium capillifolium, or dogfennel (also written "dog fennel"), is a North American perennial herbaceous plant in the family Asteraceae, native to the eastern and south-central United States. It is generally between 50 cm and 2 meters tall with several stems that fork from a substantial base. The stems and base are covered in leaves so dissected that they resemble branching green threads coming out of the stem in fractal patterns. When crushed, the leaves and flowers smell rather unpleasant.

Compounds documented for Eupatorium capillifolium 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 Eupatorium capillifolium has left across the world's sequence archives.

The complete instruction manualEupatorium capillifolium 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. Click any value below to see the underlying records and sources.

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.
