    • Abstract


      The extrafloral nectaries ofBignonia illicium occur on the foliage leaves, while the toral nectary is found on the torus around the ovary base. The extrafloral (foliar) nectary is non-vascularised and consists of a single layered secretory tissue followed by a large single celled stalk and single layered foot. The toral nectary is composed of isodiametric parenchymatous cells supplied with phloem. Symbiotic relationship between the animal visitors and the nectaries and their probable functions are discussed.
