Abstract:
The current research included a study of the morphological characteristics of five species of the genus Convolvulus L. of the Convolvulacaea family, widespread in Latakia Governorate, during the two years (2021-2022), using optical and scanning electron microscopes. The results showed that the pollen grains of the genus are medium to large in size, with three germinal lines, 3-zonocolpate, with various shapes: C.althaeoides, C.arvensis, C.cantabrica, and C.scammonia, and the prolate-elongated form of C.scammonia, and the oblate-spheroidal form of C.scammonia. betanocefolius and the sub-prolate shape of the species C.cantabrica. The decorations are notched. The smallest pollen grains were of the species C.cantabrica (52.2 – 60 ×((48.66 – 54.8) μm For species within a genus, they provide valuable information for distinguishing between similar species.
Key words: Convolvulacaea, Convolvulus L., pollen grains , 3-zonocolpate, electron microscope SEM .
