| The present study deals with the morphological characteristics of pollen grains of eleven Taxa which belong to different genera of the Apiaceae family growing wild in Salah Al-Deen governorate -Iraq using a light microscope. These are Cachrys papillaris Boiss, Conium maculatum, Carum carvi L., Orlaya daucoides (L.), Lisaea strigosa, Turgenia latifolia (L.) Hoffm, Hellenocarum amplifolium Boiss, Trigonoscidium viscidulum Boiss, Scandix iberica M., Zosima absinthifolia (vent), and Malabaila secacul (Mill.) Boiss. The results of the current study show that all pollen grains of the studied Taxa are monads and isopolar, and all are of the Tricolporate type. The study includes the morphological characteristics of the pollen grains in terms of the pollen grain's shape and size, the pores' dimensions, the exine's thickness, and its ornamentation. The sizes of the pollen grains range from small in the two taxa C. carvi and C. papillaris, while being medium in seven species, namely C. maculatum, T. viscidulum, S. iberica, Z. absinthifolia, M. secacul, H. amplifolium, and O. daucoides and large in the two species of T. latifolia and L. strigosa. They were oblong in all the studied species except C. carvi, O. daucoides, and H. amplifolium and also showed differences in the shape of both the equatorial and polar views. The findings from the study hold significant taxonomic value for the isolation of the species examined. |
