Abstract
Recent fieldwork has revealed a new species of Virotia, a genus of Proteaceae endemic to New Caledonia. This understory monocaulous shrub or tree was found in two nearby rainforests on ultramafic substrate in the Poro region. We report high concentrations of manganese (10,900 mg.g(-1)) and nickel (2,900 mg.g(-1)) in dry leaves of this species. This is one of the few cases of simultaneous hyperaccumulation of these metals in angiosperms. This rare micro-endemic species is given a conservation status of critically endangered due to the impact of nickel mining, fire and fragmentation on its habitat.
