Meaning and Definition
The pollination of a flower by pollen from another flower on the same plant.
A specific mode of self-pollination in plants where pollen transfer occurs between flowers of the same individual, distinct from both outcrossing (xenogamy) and within-flower selfing (autogamy).

Common Mistakes When Using “geitonogamy”
- Misspelling as 'geitonogamy' (missing 'i'), 'geotonogamy', or 'getonogamy'.
- Confusing it with 'autogamy' (self-pollination within a single flower).
- Using it to refer to animal mating systems (incorrect).
FAQ
Frequently Asked Questions
Yes, it is a form of self-pollination (or more precisely, within-plant pollination), distinct from autogamy (within-flower selfing) but with similar genetic consequences of inbreeding.
It represents a trade-off. It ensures seed set when pollinators or mates are scarce (reproductive assurance) but reduces genetic diversity, which can lower offspring fitness (inbreeding depression).
It is common in plants with many closely spaced flowers that bloom simultaneously, such as in inflorescences of grasses, orchids, and many tree species (e.g., conifers).
In agriculture and breeding, it can be reduced by spatial isolation of plants, manipulating flowering times, or using pollinators that move between plants. Some plants have evolved floral mechanisms (like dichogamy) to prevent it.
The pollination of a flower by pollen from another flower on the same plant.
Geitonogamy is usually specialized, technical, academic in register.
Geitonogamy: in British English it is pronounced /ˌɡaɪtə(ʊ)ˈnɒɡəmi/, and in American English it is pronounced /ˌɡaɪtəˈnɑːɡəmi/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Imagine a GIANT (sounds like 'geito-') plant, but it's LONELY ('no' in the middle) and can't find a partner from another plant, so it has a GAME ('gamy') of passing pollen between its own flowers.
Conceptual Metaphor
Plant reproduction as a mating strategy; flowers as individuals within a family (the plant) breeding with close relatives.
