Leaf Epidermal Studies in Some Araceae

Investigations on the epidermal morphology, stomatal ontogeny of the members of Araceae, bring out, Foliar epidermal structure of 16 species of aroids is described. The epidermal cells are mostly isodiametric and polygonal, occasionally undulated or wavy with thick or thin anticlinal walls arranged irregularly or in vertical rows. Leaves are hypostomatic to amphistomatic. Stomatal type is paracytic to tetracytic, stomatal development is perigenous.
