Abstract
In Ophiorrhiza mungos L. the first division of the microspore nucleus gives rise to a large vegetative nucleus and a smaller generative nucleus. The vegetative nucleus subsequently fragments into a number of irregularly sized particles. These vegetative nuclear bodies move to and flow out of the three germ pores to form three spherical buds on the developing pollen grains. The 'pollen buds' are shed off from the pollen proper before dehiscence. The uninucleate grains readily germinate in vitro, and the single generative nucleus undergoes normal division to give rise to two sperm nuclei.
