Abstract: 
Pollen morphology is one of the important tools for the taxonomic studies and helps in the identification of medicinal plants. Pollen characterization of three species of Ocimum viz., Ocimum tenuiflorum, Ocimum gratissimum, and Ocimum basilicum collected from Telangana region of South India during 2022 was carried out by using Light Microscope (LM). The pollen grains showed variations in size, shape, with amb spheroidal to ellipsoidal. All the species had hexacolpate pollen grains. The exine is subtectate and sporoderm ornamentation is reticulate with variations in heterobrochate conditions. The lumina varied from penta, hexa, polygonal to irregular form. The plants studied in the present work were known for their medicinal use having antibacterial and antiviral properties and most important in traditional system of medicine.
