EtymologyArceuthobium means juniper-like, from the Greek: arkeuthos = juniper + bios = life; pusillum is Latin for very small or tiny.

DescriptionDwarf mistletoe is a tiny, slightly woody plant only 1/2" tall that commonly parasitizes young branches of black spruce (Picea mariana) and ocassionally other conifers. Barely resembling a flowering plant, it looks like a brownish growth among the conifer needles, with a stem only 3/16 -- 5/8" long. Dwarf mistletoe also causes conspicuous "witches brooms" of dense branches on the infected host. The smooth stems are brownish or olive or purplish, can be simple or branched, and are brittle at the base.
