Geitonogamy

   Also found in: Dictionary/thesaurus, Wikipedia 0.01 sec.
geitonogamy [‚gīt·ən′äg·ə·mē]
(botany)
Pollination and fertilization of one flower by another on the same plant.

Geitonogamy 

cross-pollination within the same plant as a result of the transfer of pollen by insects or by the wind from one flower to another. Geitonogamy is known to occur, for instance, among carrots during their flowering when flies crawl over the entire raceme and transfer the pollen picked up on one flower to the stigma of the pistil of another. Occasionally certain plants (toadflax, for example) do not produce seeds in geitonogamy.

Treatment 2) The flower was emasculated as above, but not bagged, so that seeds that matured would be the result of either geitonogamy (in which an ovule is fertilized by pollen from a different flower on the same plant) or xenogamy (in which the pollen is transferred from a different individual), but not intrafloral self-pollination.
2001) suggest that reproductive losses to geitonogamy are more severe for male than for female fitness, providing an opportunity for gender-specific selection in the absence of sexual selection.
