Phoradendron coryae, Cory's mistletoe or oak mistletoe, is a hemiparasitic plant native to the southwestern United States and northern Mexico. It is reported from Arizona, New Mexico, Texas, Chihuahua, Coahuila and Sonora.Hawksworth, F.G., & D. Wiens. 1993. Viscaceae, Mistletoe Family. Journal of the Arizona-Nevada Academy of Science 27:241-245. The species generally grows on oaks (Quercus spp.) but has also been found on Condalia, Berberis, Vaquelinia and Sideroxylon. It has larger leaves than many other mistletoes of the region, up to 3 cm long. Leaves and flowers are pubescent. Berries are white, with short hairs around the persistent perianth.

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 Phoradendron coryae has left across the world's sequence archives.

09Environmental DNA1 detections
Where the DNA of Phoradendron coryae 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 strong is each trace?
DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.
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.
