Functional significance of pollen aggregates in angiosperms is discussed with reference to the number of ovules per ovary, number of seeds per fruit, polyad stigma relationship and correlation with the pollen type. Information regarding the pollination and breeding systems is also presented . it is shown that pollen aggregates have repeatedly evolved in angiosperms.
