Description & ecology

Leaf Ni measured at 9,240–12,860 µg/g, with chelidonic and malic acid as the dominant organic-acid ligands; the hyperaccumulating taxon is B. zeyheri subsp. rehmannii var. rogersiana.

One of only five confirmed South African nickel hyperaccumulators, all Asteraceae (Mesjasz-Przybyłowicz et al. 2020).
