Euphorbia antisyphilitica is a species of flowering plant in the spurge family Euphorbiaceae. It is native to the Trans-Pecos of Texas and southern New Mexico in the United States as well as Chihuahua, Coahuila, Hidalgo, and Querétaro in Mexico. Common names include candelilla and wax plant, but the latter is more often applied to members of the unrelated genus Hoya. It is shrubby and has densely clustered, erect, essentially leafless stems that are covered in wax to prevent transpiration.

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 Euphorbia antisyphilitica has left across the world's sequence archives.

09Environmental DNA2 detections
Where the DNA of Euphorbia antisyphilitica 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.
