After pollination, the downy buds covered in fine hair break open to release countless little winged seeds on to the wind.

授粉后，长满细毛的绒毛芽破开，向风中释放出无数带翅膀的小种子。

After they  go to seed, each plant has tens of thousands of winged seeds that are taken away by the wind.

结籽后，每株植物都有数以万计的带翅种子，这些种子会被风带走。

And for their first hundred million years, they were pollinated by wind or water blowing or washing their winged seeds on their way.

在他们的头一亿年里，他们通过风或水的吹动或在途中清洗有翼的种子来授粉。
