Most studies on holoparasitic plants have focused on taxonomic or systematic issues. The objective of this study
was to examine the ecological aspects of parasitism of Langsdorffia hypogaea (Balanophoraceae) in the Pantanal
wetlands. Individuals of L. hypogaea were dug out by hand and the host trees were identified. Eighty-eight percent
of host trees exhibited zoochory dispersal syndrome. Protium heptaphyllum and Cordiera sessilis represented 50% of
the sampled trees. Both species are evergreen and are preferentially shade-tolerant species growing under the canopy
of other trees. Fecal sample of collared peccaries (Pecari tajacu) had seeds from both the host tree (Protium sp.) and
the parasite L. hypogaea. We therefore propose the hypothesis that P. tajacu play a role as a seed disperser and may
affect root parasitism
