Results of partial tests of relationships between selected individual anatomical traits of plants (in rows) and their adult plant height and elevation.

AH headed columns refer to ahistorical comparisons (i.e without phylogenetic corrections), while PC headed columns refer to models with a correction for phylogenetic relatedness. Individual cells in AH and PC columns show Type I error probability estimates (adjusted by Bonferroni correction within test families) or ns when adjusted with P≥0.10. The percentage of trait variation explained by phylogenetic relatedness (Evol) between the species, and ecological preferences (Ecol) in the phylogeny-corrected analysis, are shown. Response (Res) columns show positive (+) or negative (−) relationships between the anatomic trait value and the predictor.
