This research included a comprehensive (micro-phenotypic) pollen study that included 8 wild plant species are (P.bornmuelleri, P.curviscapum, P.polychaetum, P.tauricola, P.pavoninum, P.rhoeas var. himerense, P.rhoeas var. strigosum and P.setigerum) belonging to the genus Papaver of the Papaveraceae family growing in middle and northern Iraq. The samples were collected during 2023-2024 growing season. Approximately 17 field tours were carried out, including the central and northern governorates, in addition to a comprehensive survey of preserved herbarium samples in the Iraqi National Herbarium and other universities Herbarium for detection. Pollen grains were examined for the arrangement of species using a Light Microscope (LM) and Scanning Electron Microscope (SEM). It was found that the all of pollen grains were of the tricolpate type, and the species were classified based on the number of apertures and colpi and pollen grain shape, and its size varied between small and medium size (P.curviscapum, P.rhoeas var. himerense, P.rhoeas var. strigosum were medium size) and (P.bornmuelleri, P.polychaetum, P.tauricola, P.pavoninum and P.setigerum were small size), in addition to studying the surface ornamentation of the external grain wall (exine ornamentation).
