Extraordinary uptake of nickel (Ni), reaching concentrations of 0.1-5.0%, c. 1000 times greater than those usually found in flowering plants, has been observed previously in c, 190 species that grow on Ni-rich serpentine soils derived from ultramafic rocks in various parts of the world. These so-called hyperaccumulators of Ni include c. 50 species from the rich ultramafic flora of New Caledonia and c. 80 species from the Brassicaceae of Mediterranean Europe and Turkey. A study of a limited part (the families Buxaceae and Euphorbiaceae) of the very large ultramafic flora of Cuba has now identified this as the home of at least 80 hyperaccumulators, the largest number jet found in any one count..View full abstract
