Morphological studies of the pollen grains of Wadi El-Natrun plants, West Nile Delta, Egypt

Pollen morphology is regarded as an additional tool for solving taxonomic problems at the family, generic, or species level. Seventy-three flowering plants, trees, shrubs, and herbs were collected from the Wadi El-Natrun region (West Nile Delta, Egypt) from March to July 2008. They were extracted for their pollen grains. The pollen was mounted on glass slides, examined using a light microscope, photographed, and identified. The identified pollen grains were conserved in the herbarium of the Environmental Studies and Research Institute (ESRI) Minufiya University, Sadat City, Egypt, as reference key pollen from the Wadi El-Natrun area for palynologists, botanists, taxonomists, and workers in other, related, sciences.
