Abstract
Arceuthobium pendens, a parasite of the pinyonsPinus discolor andP. cembroides, is described from San Luis Potosí and Veracruz, Mexico. This andA. divaricatum Engelm. are the only dwarf mistletoes known to parasitize pinyons.Arceuthobium pendens is distinct fromA. divaricatum Engelm. in its long, slender, greenish shoots, formation of systemic witches brooms, and frequency on various species of pinyons. With the discovery of this new species, 19 dwarf mistletoes are known from Mexico.
