Ranunculus arvensis L. has high plasticity and adaptability to different environmental conditions. The aim of the study was to explore the morphological characteristics of pollen of four populations Ranunculus arvensis L. that highly reflect the parameters of the environmental variability. The field size, aperture and surface of the pollen were studied by Scanning Electron Microscopy (SEM) analysis. The fertility of pollen was established. The most variable was the size (diameter) of the pollen in Ranunculus arvensis L. from different localities of Bulgaria. The shape and nature of the aperture remained the same and did not depend on localities. The fertility was not related to the habitat of the taxa Ranunculus arvensis L.
