Clematis occidentalis is een Clematis-soort uit de Atragene groep die van nature in de bergen en heuvels van zowel het oosten alsook het westen van Noord-Amerika voorkomt, maar niet in het midden. De plant werd in 1815 door de Deense botanicus Jens Wilken Hornemann voor het eerst beschreven en benoemd en vervolgens in 1824 door de Zwitserse botanicus Augustin Pyramus de Candolle geldig gepubliceerd. De Amerikaanse naam is "purple clematis", "purple virgin's bower" of "western blue virgin's bower" en mag niet verwisseld worden met de soort "virgin's bower".

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 Clematis occidentalis has left across the world's sequence archives.

The complete instruction manualClematis occidentalis 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 Clematis occidentalis 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.
