Fatoua villosa is an annual herb in the Moraceae (mulberry) family. Common names include mulberry weed, crabweed, or hairy crabweed in English, Kuwakusa (クワクサ（桑草）/クワ科クワクサ属) in Japanese, and Shui she ma (小蛇麻 or 水蛇麻) in Mandarin. It is native to eastern Asia, some Pacific islands, and parts of Australia (specifically in two Australian states (Western and Queensland) Bismarck Archipelago, China, Japan, Indonesia (Java, Maluku, Sulawesi), Korea, Lesser Sunda Island, New Guinea, Philippines, Solomon Islands, Taiwan, Thailand, Vietnam). It has become an invasive species in the United States where it grows in disturbed areas such as flowerbeds, greenhouses, and agricultural fields.

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 Fatoua villosa has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
The complete instruction manual Fatoua villosa 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 Fatoua villosa 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.
Signal
Where its DNA was found
How strong is each trace?
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.
