We follow Patrick Blanc during his first botanical trip in New Caledonia aka « Le Caillou », this rocky island harboring one of the highest levels of endemism in the plant kingdom. This southernmost part of the island is characterized by the red ultramafic superficial soils so rich in heavy toxic metals like nickel, chromium and cobalt, thus driving the plant evolution towards a resistance to this toxicity as well as facing the recurrent fires and the mining exploitation. Among the different adaptations, the monocaulous small trees with a terminal leaf rosette allow the accumulation of dead leaves falling from the canopy thus creating an aerial humus which releases the useful minerals flowing down along the trunk.
