Abstract

• The pollen morphology of twelve species belonging to six genera of Convolvulaceae familiy were studied in the present paper. The pollen grains of all specimens were collected from Shwedaung Township, Bago Region (west). The pollen morphological characteristics of all species were studied. The aperture type and sculpture pattern of each grain were examined by electric microscope. Three types of aperture (tricolpate, pentacolpate and porate) and four types of exine sculpture echinate, granulate, reticulate and striato-reticulate are found. The outline of pollen images for each species were presented by polar and equatorial view and then were recorded by photomicrographs of clear cut pollen images and types of habit and flower.
