Spergularia villosa is a species of flowering plant in the family Caryophyllaceae known by the common name hairy sandspurry. It is native to southern South America, and it is known in the southwestern United States and Baja California as an introduced species and casual weed. It grows in a wide variety of habitat types. It is a small perennial herb producing a sprawling stem up to 30 centimeters long with a woody base. It is coated in glandular hairs. The leaves are generally linear in shape and measure a few centimeters long. They are accompanied by dull white lance-shaped stipules. The flowers have hairy, glandular sepals and five oval whitish petals.

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 Spergularia villosa has left across the world's sequence archives.

09Environmental DNA1 detections
Where the DNA of Spergularia 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.

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.
