【释义】：

Any of several plants，including the Amaranthus genus and Russian thistle(Salsola kali)，whose branching upper parts come loose from the roots and are driven by the wind across the prairie．The plant，like sagebrush，has become a symbol of the American West，as in song lyrics such as“tumbling along with the tumbling tumbleweed．”One old belief has it that God put tumbleweed here to show cowboys which way the wind is blowing．

一种植物名，指“风滚草”，这一属植物包括Amaranthus genus和俄国蓟(猪尾草属)，根部以上是松散的枝条，当风掠过草原时，这些松散的枝条就会随风滚动。这种植物象三齿蒿一样，成为美国西部的象征，正如歌中所唱的：“随着滚动的风滚草滚动”。有一个古老的信念，说上帝把风滚草放在美国西部是为了向牛仔显示风向。
