Abstract The pollination ofVigna vexillata (Leguminosae-Papilionoideae) by a carpenter bee,Xylocopa gualanensis (Hymenoptera-Anthophoridae) was studied in a secondary vegetation in Costa Rica. The bees were observed foraging onV. vexillata only in early mornings. Visits on individual flowers lasted about 7–8 seconds. Flower—pollen vector interactions are described and illustrated. By its pressure on the left-hand wing- and keel-petal in the asymmetrical flower, the weight of the bee causes the upper bearded part of the style along with the upper free parts of the stamens to slip out of the rigid keel-beak, “hugging” the bee over the dorsal part of its head and thorax. The occurrence of nototribic pollination inVigna and related genera is discussed.
