Résumé
Pollen morphological descriptions and photographic illustrations based on light microscope analysis are provided for 30 species belonging to 18 families from Erkwit area in the eastern of Sudan. The pollen characteristics among species in the same family are similar to each other. The results indicate that pollen characters may be significant in taxonomical studies. The effect of various chemicals on the size of pollen grains was studied. The size of acetolysed grains was affected by the treatment prior to acetolysis, and the measurements taken were corrected by a correction factor (L), The correlation between pollen size and chemical treatments, as suggested previously by (Christensen, 1946), is confirmed by our data
