Abstract
The anther wall ofC. koenigii showed the epidermis, endothecium, middle layer and tapetum. Cytokinesis in the pollen mother cells was successive and isobilateral type of tetrads were formed. The mature pollen grains were three-celled. The development of the embryo sac conformed to the Polygonum type. The antipodal cells increased in number and persisted in the young fruit. Twin embryo sacs occurred in about 30% of the ovules. Endosperm development was nuclear.
