Arceuthobium oxycedri is commonly known as dwarf mistletoe and grows on and infects cypress species. The semi-parasitic plant was observed in three locations of Juniper Reza Abad in Semnan Province, Chahar Bagh Area of Gorgan and Zanjan Province. In this study, the anatomical and micromorphological characteristics of the species were evaluated to facilitate the identification of this semi-parasitic species in Golestan province. The outcomes of the analysis indicated that the estimation of infestation rate in dwarf shrub trees is unattainable through factors such as canopy percentage, stand gender, slope percentage, and slope orientation. Examination of the stem's transverse section revealed that, across all three elevations, there were no variations in brain size between the semicircular cross-section and the sink's thickness. Analysis of pollen demonstrated that every pollen grain is classified as Monad, exhibiting three to five deep and asymmetric grooves of varying sizes (tricolpate). In regards to their morphology, they exhibit an oblatespheroidal shape adorned with sharp exine decorations. Overall, given the novelty of this study on dwarf mistletoe species, the discoveries hold significant systematic implications for the identification of analogous species documented in alternative juniper habitats within Iran.
