Abstract
The occurrence, morphology, ontogeny, structure and preliminary nectar analysis of floral and extrafloral nectaries are studied inKigelia pinnata of the Bignoniaceae. The extrafloral nectaries occur on foliage leaves, sepals and outer wall of the ovary, while the floral nectary is situated around the ovary base as an annular, massive, yellowish ring on the torus. The extrafloral nectaries originate from a single nectary initial. The floral nectary develops from a group of parenchymatous cells on the torus. The extrafloral nectaries are differentiated into multicellular foot, stalk and cupular or patelliform head. The floral nectary consists of parenchymatous tissue. The floral nectaries are supplied with phloem tissue. The secretion is copious in floral nectary. Function of the nectary, preliminary nectar analysis, and symbiotic relation between nectaries and animal visitors are discussed.
