Abstract
Pollen morphology of 12 species of the genus Silene belonging to 8 sections were investigated by using Light Microscope SEM and TEM. Three groups of exine type of the pollen grains were shown, punctate, punctate-undulate and semi-reticulate. TEM micrographs show the operculate, non-annulate pore are made of the same layers of exine i.e. tectum, columellae and foot layer. This emphasizes the retention o the Caryophyllaceae in the Centrospermae.
