Phoradendron juniperinum Engelmann ex Gray subsp. juniperinum
(Juniper Mistletoe)

Family: Santalaceae, formerly Viscaceae

Status: Native

Synonyms:
None

Phoradendron juniperinum subsp. juniperinum is found growing on junipers at lower to middle elevation. It appears to be all jointed stem, although there are scale like leaves. This is one of the most common mistletoes in the Gila National Forest. Large knots can form at the junction of host and parasite tissue, where modified parasite roots called "haustoria" penetrate into the host. The berry has a thin outer layer covering a sticky gelatinous interior that coats the small seed which is slightly hairy and shaped like a turnip.
