Phoradendron densum Trel. is a species of flowering plant in the sandalwood family known by the common name dense mistletoe. It is native to the western United States and northwestern Mexico, where it grows in various types of woodland habitat. It has been reported from California, Oregon, Arizona and Baja California.Hawksworth, F.G., & D. Wiens. 1993. Viscaceae, Mistletoe Family. Journal of the Arizona-Nevada Academy of Science 27:241-245. This mistletoe parasitizes species of cypress, including Arizona cypress (Cupressus arizonica),Hosts of True Mistletoes and juniper (Juniperus spp.). It can be found tangled in the branches of its host tree, extending its own erect branches 30 to 50 centimeters. It has green leaves around a centimeter long and half a centimeter wide. It is dioecious, with male and female plants producing different forms of inflorescence with round, knoblike flowers. The female flowers yield spherical berries each about 4 millimeters wide and yellowish or pale pink when ripe.

Where the DNA of Phoradendron densum 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.
