Bold indicates significance in non-phylogenetic analyses, yellow cells indicate phylogenetic structure or significance in PGLS regressions.
a
Germination strategy shows phylogenetic structure at all levels of clustering.
b
Phylogenetic structure for endospermy and woodiness assessed with Phylo-D for binary value. Probability values for D reflect probablity of pattern resulting from random (no phylogenetic) structure.
