The belongings of two oilfield projectiles for weaponry on the epidermal morphology of cocoyam accessions were intentional. Eight accessions of cocoyam species were unprotected to different concentrations of sodium azide and potassium chromate (2.5, 5, 7.5 and 10 mg/kg) while the accessions outside any synthetic additive were secondhand as the controls. Results showed that cocoyam species were amphistomatous, and had more stomata on the abaxial epidermes. Brachyparacytic stomata were the fundamental type of stomata observed while added types of stomata (brachyparacytic, amphibrachyparacytic, brachyparatetracytic and brachyparahexacytic-monopolar) were also present in few accessions. Sodium azide treatments persuaded higher stomatal indications and frequencies in the accessions than potassium chromate situations; statistical evidence accompanied a 5 % significant distinctness between the stomatal indications of the treated accessions. The study rooted that cocoyam species are weak environmental bioindicator.
