Tissue concentrations of 12 mineral elements (Al, Ca, Cu, Fe, K, Mg, Mn, amino‐N, Na, P, Si, and Zn) were measured in an autoparasitic mistletoe ( Phoradendron californicum ), the parasitic mistletoe on which it was growing ( Phoradendron californicum ), and the host tree ( Cercidium floridum ). Mineral concentrations in the autoparasite were typically 1.1–1.3 times higher than in the parasite. Mineral concentrations of all elements except Ca, Fe, Mg, Mn, and Si were higher in the parasitic mistletoe than its host. Mineral concentration differences are discussed relative to accumulation via the transpiration stream and translocation within the host via the phloem.
