Description & ecology
Metallicolous populations accumulate up to ~80,000 µg Tl/g in nature (Regini 2025) — the highest thallium concentration recorded in any plant; an Allchar population was measured at 79,200 µg/g (cited in Jakovljević et al. 2025).
Facultative: only metallicolous populations hyperaccumulate; photosynthetic decline sets in around 15,000 µg/g leaf Tl.
