The article includes the palynomorphological study of some species of the genus Achillea in Albania. In this article submitted comparative features of the species: Achillea abrotanoides, Achillea ageratifolia, Achillea clavennae, Achillea chrysocoma dhe Achillea millefolium. The material for the study was obtained in National Herbarium in Tirana. For the study of palynomorphological features are analyzed 31 pollen grains from each species. The treatment of material is made with acetolysis method and basic fuchsine. The fixing of pollen grains is made with glycerin gelatin. The study and photos of pollen grains are realized with light microscope with 1000x power. Between the plant species included in the study are differences and similarities regarding the palynological features such as: dimension of pollen grain, thickness of exine, length of spines, width of spines. The pollen grains of plants above are tricolporate. The shape of pollen grains by the outline appears spheroidal or prolate spheroidal. The exine appears thick and has two-layers. The sculpture of exine is echinate. DOI: 10.5901/ajis.2016.v5n3s1p74
