520	3		_aThe genus Macroptilium (Benth.)Urban is characterised by having asymmetrical flowers and spirally coiled styles. The pollen is presented secondarily by a stylar brush. Floral structures of four species were analysed at macroscopical and microscopical levels as to their role in floral functioning. The vexillum has two auricles with globose and striate epidermic cells. In all species investigated, wing and keel petals are neatly connected at their bases. The distal parts of the keel form kind of an application tube and the petals are fused to each other by rows of striate interpenetrating trichomes along their upper edges and by genuine fusion along their lower side. Macroptilium has a ring-shaped nectary, narrow and lobed asymmetrically. It is located between the base of the ovary and the staminal furrow, and is attached to the receptacle. Nectar, which is secreted trough open stomates, collects between the nectary and the staminal furrow. We conclude that the four species studied have floral structures fitting into the melittophily syndrome.
