The tree is called Pycnandra acuminata, and it grows in the rainforests in what are called ultramafic soils.

这种树叫做尖尾木桐，它生长在热带雨林的超镁铁质土壤中。

Pycnandra acuminata also basically quarantines the nickel in cells that are separate from other parts of the plant.

尖尾木桐还有另一种方法，简言之就是将镍隔离于远离其他部位的细胞中。

But the roots of Pycnandra acuminata guzzle up that metal, and the plant has about 250 grams of nickel per kilogram of sap.

而尖尾木桐的根会疯狂吸收镍，其每千克树液中约含250克镍。
