Description & ecology

VALUE AS STATED AT SOURCE (Jaffré, Pillon, Thomine & Merlot 2013, Front. Plant Sci. 4:279, Supplementary Table, read 2026-09-13): Geissois pruinosa (all varieties) — 40 foliar analyses, 31 in the 1,000–10,000 ppm band and 9 ≥10,000 ppm, range 3,000–15,106 µg g⁻¹ Ni DW (Jaffré et al. 1979 data plus new measurements).

Promoted and corrected 2026-09-13: 15,000 (compilation) → 15,106, the exact maximum in the measuring team's data table.

Almost all Geissois species on ultramafic soils hyperaccumulate nickel (Jaffré et al. 2013); the genus was among the first New Caledonian groups reported with >1% leaf Ni, and G. pruinosa is a high-biomass phytomining candidate.
