Pollination by Wind

• Large quantities of light pollen must be produced to better the chances of ripe pollen of one species landing on the stigma of the same species
• Grass has small, inconspicuous flowers without any bright petals
• Petals and sepals are often absent for better exposure to wind
• No nectar is produced, no scent
• The flowers are carried in groups, close to each other, at the tips of long stems
• long, thin filaments hang out of the flowers and are easily shaken by the wind
• anthers are large and release large quantities of pollen
• pollen grains are small and light and easily carried by the wind
• the stigmas are long and feather-like with a large surface area, they are suspended outside the flower, easily trapping pollen
