Serpentines are reported to occur over wide areas at or near the surface in the Andaman group of islands of India. Rutland Island and Chidyatappu in South Andaman and the Saddle Hills in North Andaman possess ophiolites in contiguous blocks covering appreciable areas. The soils had a low nutrient content and high concentrations of nickel, varying from 2700 to 10100μgg-1. In total, 11 hyperaccumulators of nickel were identified from the Andaman group, belonging to eight genera and seven families. Of these, Dichapetalum gelonioides (Roxb.) Engl. subsp. andamanicum (King) Leenh. and Rinorea bengalensis O.Kuntze accumulated nickel up to 30000μgg-1 dry leaf. The vegetation was evergreen, broad-leaved sclerophyllous scrub, with trees never exceeding 4-5m in height. © CSIRO 2015. Source
