ABSTRACT

Utricularia gibba L. ssp. exoleta belongs to the family Lentibulariaceae (order Personatae). It is a small carnivorous plant without roots, which Boats just below the surface of the water. The fine filiform leaves are alternatively formed on a branched axis, some of them bearing hollow, bladder-like animal traps. This chapter presents data on the flower morphology of U. gibba ssp. Exoleta. It discusses the effect of animal-derived nutritive materials, effect of photoperiod and light intensity, effect of plant growth regulators on the flowering of U. gibba ssp. Exoleta. When U. gibba spp. exoleta plants were axenically grown on a standard nutrient medium there was no flowering, whereas profuse flowering was observed when the medium was supplemented with animal-derived nutritive materials. The mature flowers were formed after a period of 70 days; however, after 13 days there were already indications of flower bud formation.
