Petioles at the base of the leaves sport a string of ingeniously constructed traps.

叶子尾部的卷须挑起一个个精巧的捕虫笼。

We should boil lupine leaves, clover, starchy petioles, and saxifrage rootstocks like the Indians.

我们应该像印第安人一样煮羽扇豆叶、三叶草、含淀粉的叶柄和虎耳草砧木。

I touched them gently on their leaves, and they closed up along the petiole.

我轻轻地触碰它们的叶子，它们就沿着叶柄闭合起来。
