Geitonogamy involves transfer of pollen grains from the anther to the stigma of another flower of the same plant. Autogamy is a type of self-pollination in which an intersexual or perfect flower is pollinated by its own pollen, i.e., it involves the transfer of pollen grains from anther to stigma of the same flower. Xenogamy involves transfer of pollen grains from anther to the stigma of a different plant. Cleistogamy is a phenomenon in which flowers do not open at all, therefore show self-fertilisation and autogamy.
