Mammillaria barbata Engelm.Engelm. in Wisliz., Memoir of a Tour to Northern Mexico: connected with Col. Doniphan's Expedition in 1846 and 1847 105–106. 1848. is a small cactus native to Chihuahua, Sonora, and Durango, with the common name greenflower nipple cactus. It is found in mountainous locations in the Sierra Madre Occidental.Laferrière, Joseph E. 1994b. Vegetation and flora of the Mountain Pima village of Nabogame, Chihuahua, Mexico. Phytologia 77:102-140. It has delicate white to pink flowers. The fruits are red and oblong. They are edible but too small to be of much food value to humans.Laferrière, Joseph E., Charles W. Weber and Edwin A. Kohlhepp. 1991. Use and nutritional composition of some traditional Mountain Pima plant foods. Journal of Ethnobiology 11(1):93-114.

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 Cochemiea barbata has left across the world's sequence archives.

Where the DNA of Cochemiea barbata 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.
