About

Arceuthobium californicum is a species of dwarf mistletoe commonly known as sugar pine dwarf mistletoe. It is a small shrub endemic to California that parasitizes the sugar pine (Pinus lambertiana). Although detrimental to the health of its host, it is ecologically important as a food source for wildlife and because the witch's brooms that it sometimes induces on host trees provide valuable habitat for birds and small rodents.

Where it grows

The range of A. californicum lies entirely within the range of its host, Pinus lambertiana, but it has a narrower geographic and elevational range than its host. In particular, A. californicum is limited to California; earlier reports of its presence in southwestern Oregon represent the previously undescribed species A. monticola. This makes A. californicum one of three species of mistletoe endemic to California, the others being A. littorum and A. occidentale.
