ABSTRACT
A number of hemiparasite plants belonging to the mistletoe species, which are taxonomically related to the European mistletoe (Viscum album L.), grow in Argentina. According to the work carried out by Abbiatti (1946), 23 different mistletoe species grow in diverse phytogeographic regions of the country with the exception of the Pampean savannah, the Patagonian steppes and the arid Andean regions. The Monte (shrub-like) Formation due to the abundance of leguminous trees, which are the preferred mistletoe hosts, is the most densely populated.
