Field Maple Lionfish ( Acer campestre ): A typical example of fruit spread by the wind.
Anemochoria (from the Greek. Άνεμος - wind and χωρέω - go, spread) - the distribution of diasporas (fruits, seeds, spores and other plant primordia) by air currents. It is an adaptive sign of seeds and fruits.
Anemochoria is promoted by the small size and light weight of seeds ( orchid , broomrape ), as well as hairs on seeds and fruits ( willow , poplar ), winged outgrowths ( elms , ash , maples ), awns ( feather grass ) and other devices. Light seeds with lionfish spread over distances from 20-30 meters (linden, ash, maple, fir), up to several tens (pine, spruce, alder, larch), hundreds of meters (birch, aspen, willow) and even kilometers.
