Flower ecologists have distinguished the wind pollinators , i.e. the anemophilous plants from the zoidogamous plants .

花生态学家把风媒传粉种，即风媒植物，同动物媒植物区别开来。

Furthermore , those anemophilous plants producting larger or spherical pollen grains usually have a stronger inclination of single-species forestation .

并且，产大个体或球状花粉者，往往具有较强的单种成林倾向。
