Abstract

The floral morphology of the three papilionaceous species: Ononis vaginalis Vahl , Dolichos lablab L. andCrotalaria aegyptiaca Benth. was studied to trace the organ vascularization. Vascular complexes to the sepals,the petals and the stamens were recorded in the three species. Three cases of stamen adelphy were met with viz.monadelphy, diadelphy and pseudomonadelphy. In the latter case a basal fenestration in the staminal tube existsas an access to successful insect pollination. A foliar nature was determined for the nectary disc where present.In the three species the carpel is supplied by the basic number; one dorsal and two ventral traces.
