It is a parasitic plant that grows as a shrub on the branches and trunks of Southwestern white pine (Pinus strobiformis, sometimes treated as Pinus reflexa) trees in Arizona, New Mexico and Coahuila. In turn, it is often parasitized by species of fungi. Like with many dwarf mistletoe species, populations of A. apachecum impact the ecology of their environments significantly, degrading the health of host trees but providing food and creating habitat for various animals....read more on Wikipedia.
