Popis:	Dwarf mistletoes ( Arceuthobium spp.) are important plants in temperate forests of Mexico due to their high incidence. At the south side of the Papayo Hill in the “Zoquiapan y Anexas” Natural Protected Area, Mexico State, both, Arceuthobium vaginatum subsp. vaginatum and A. globosum subsp. grandicaule coexist within the same zone and, frequently, on the same host tree of the species Pinus hartwegii . We studied the vertical distribution of both species on the stem, and we registered that A. vaginatum is found more frequently to lower heights of the pines than A. globosum . These results suggest that the nutritional resources are taken in a differential manner, causing a probable competitive relation between the two species.
