La xanthorhiza est l'unique espèce représentant le genre Xanthorhiza, un des rares genres de la famille des Ranunculaceae possédant une tige lignifiée. C'est une espèce originaire de l'Est des États-Unis dont l'aire de répartition est située entre le sud du Maine au nord de la Floride et à l'Ouest de l'Ohio et dans l'Est du Texas. Le nom du genre fait référence à la racine jaune qui était utilisée pour produire une teinture jaune par les Amérindiens. L'épithète spécifique fait allusion à sa racine qui ne présente pas de ramification. Le Xanthorhiza est une plante médicinale. Elle est notamment utilisée depuis des siècles par les Cherokees, en tant qu'antibiotique. On peut infuser la plante pour ensuite boire le breuvage ayant un goût amer. elle teinte les dents en jaune lorsqu'on croque dans la racine.

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 Xanthorhiza simplicissima has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualXanthorhiza simplicissima 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 DNA6 detections
Where the DNA of Xanthorhiza simplicissima 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.
