Description & ecology
Total leaf REE ~2,300 µg/g, a rare-earth accumulator record for a temperate tree; value compiled by Goudard et al. (2024) from Robinson et al.
Notably, Goudard's own Paris-herbarium Carya specimens were below the XRF yttrium detection limit, so this is a literature-cited figure rather than a re-measured one.
