Abstract
In Berberis lycium anthers on alternate stamens dehisce, thus prolonging the male function so that pollination is affected and reproduction is ensured. The large pollen sac of each bithecous anther after the appearance of longitudinal dehiscence slit moves away from the filament while remaining attached at the tip of the connective and then orients in such a way that pollen-laden surface faces the stigma. No pollen is available to receptive stigma as pollen grains remain stuck to the anther sac. They do not get dispersed even by wind. Pollination and consequently reproduction is ensured through the intervention of insect, which does not affect pollen transfer to the stigma directly but by touching the base of the staminal filament while foraging nectar secreted by nectaries at the base of corolla, thus leading to staminal movement. This makes the dehisced anthers stick to the stigma and deposit pollen there.
