The altitudinal distribution of 10 species of hemiparasitic and parasitic plants from 4 families to the Santalalean order has been studied along a transect of 9 Km from Villa de Leiva-Arcabuco road to San Pedro de Iguaque lagoon. Four altitudinal zones are distingued and briefly described on the basis of prominent characteristics. The relation with host species are analized as other observations. Gaiadendron punctatum offers the larger range of altitudinal distribution and presents the homocaule phenomenon in roots. Phoradendron pomasquianum is reported for the first time to Colombia and Phthirusa sp. is announced as a new record.
