male anther
xenogamy









































xenogamy (greek "xenos"=stranger, "gamos"=marriage) is the transfer of pollen grains from the anther to the stigma of a different plant. this is the only type of pollination which during pollination brings genetically different types of pollen grains to the stigma. 









































the term xenogamy (along with geitonogamy and autogamy) was first suggested by kerner in 1876. 









































cross-pollination involves the transfer of pollen grains from the flower of one plant to the stigma of the flower of another plant.









































the main characteristics which facilitate cross-pollination are:

there are two methods of pollination: hydrophily and biotic pollination. in hydrophilic pollination, the pollen grains are carried through the water column by tides or currents and deposited upon an open pistillate flower. underwater video cameras have more recently revealed crustaceans, polychaetes, and amphipods swimming towards open male flowers. these creatures were attracted to the seagrass’s nutritious mucilage—a carbohydrate-rich substance that houses pollen. as the invertebrates feed on the mucilage, excess pollen grains stick to their bodies. they move from flower to flower, feeding and spreading the pollen from male to female.
