Description & ecology

VALUE AS STATED AT SOURCE (Reeves, Baker, Borhidi & Berazaín 1996, New Phytologist 133:217–224, Table 2, field leaf dry matter): L. flavicans from Cajálbana serpentine 6,710–15,500 µg g⁻¹ Ni (n=6). Read at source (full-text capture) 2026-09-13.

CORRECTION 2026-09-13: the previously listed 26,000 µg/g was REFUTED at source — it appears nowhere in the paper and was likely a conflation with L. linearifolius (13,310–27,240), the genus maximum in the same table. Corrected to the paper's own maximum, 15,500.

Earlier history: Berazaín (1981) reported 7,700 µg/g Ni for 'L. flavicans' from Loma Galindo, but the 1996 authors re-determined those specimens as L. angustifolius (now synonymised under L. flavicans). One of many Ni-hyperaccumulating Euphorbiaceae endemic to Cuba's ancient serpentine soils.

The genus Leucocroton is remarkable: all ~26 species are serpentine endemics and hyperaccumulate nickel (Jaffré et al. 2013).
