High trait variability among different populations of Protium heptaphyllum s.l. (A) Leaf and wood trait variation for multiple populations of P. heptaphyllum s.l. and color-coded by the genetic clusters identified by STRUCTURE analysis. The results confirm high variability within each population and among putatively discovered lineages. Functional traits were mapped onto a collapsed phylogeny including 24 geographically widespread populations. See Table S3 for complementary details about individual samples and Fig. 1 to access their geographic location.
