During a review of herbaria in Argentina we found a specimen of Phoradendron rusbyi, which represents the third collection of the species and a new record for the flora of Argentina. This species is a little aphyllous plant, being a member of the group of hyperparasitic mistletoes, and was found in a mixed collection, parasitizing Phoradendron bathyoryctum. A morphological description of the species is provided, and its inclusion in Phoradendron confirmed.
