Croton capitatus, known as the hogwort or woolly croton or goatweed, is an annual plant with erect, branched stems, densely covered with light brown, wooly hairs that give it a whitish appearance. It grows in dry, open areas, especially sandy and rocky soils. It is distributed across the southern United States, and elsewhere. Hogwort contains croton oil, a powerful laxative.

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 Croton capitatus has left across the world's sequence archives.

The complete instruction manualCroton capitatus 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.

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.
