Stolons, rhizomes, nodes and buds can also be used to reproduce grasses in vegetative propagation. In the tropics, certain birds and mammals are important pollinators of some flowers, but this is not the case in Britain. Self-pollination and cross-pollination are . The pistil then produces the ovules, which are fertilized by the pollen. Any one of those only has a miniscule chance of landing on the stigma of one of is own kind, so while the pollen may be carried incredible distances, the majority of the grains tend to land within just a few metres of the plant.
