Definations / Explanation :
$1.$ Geitonogamy
$2.$ Coleorrhiza
Geitonogamy - Transfer of pollen grains from the anther to the stigma of another flower of the same plant. Although geitonogamy is functionally cross-pollination involving a pollinating agent, genetically it is similar to autogamy since the pollen grains come from the same plant.
