Substrate: Lead/zinc mineralised alpine soils
Habitat: Mineralised alpine screes
Distribution: European Alps
First reported: 1977 · Reeves & Brooks
Verification: hypothesized

Description & ecology

One of very few plants with a credible foliar-lead hyperaccumulation record, from mineralised alpine screes. Lead records are treated cautiously because lead is normally root-retained and surface contamination readily inflates values.
