The present paper describes the distribution, structure, ontogeny, function of foliar nectaries and structure and ontogeny of stomata in Bignonia chamberlaynii Sims. The mature nectaries are patelliform and originate from a single papillate epidermal cell. They consist of 1-layered base (foot), 2-layered stalk and 1-2-layered palisade-like epithelial cells which secrete sugary fluid.

Tha mature stomata are anisocytic, anomocytic, paracytic, perigenous (tetracytic and amphicyclic), with a single subsidiary cell.

The ontogeny of anisocytic, paracytic and stomata with a single subsidiary cell conforms to the mesogenous type, while that of the anomocytic, tetracytic and amphicyclic ones is perigenous.

Abnormalities noticed here are contiguous (juxtaposed and superposed) stomata, stomata with a single guard cell and aborted guard cells.
