  abstract = {{U}nderstanding the distribution of traits across the angiosperm phylogeny helps map the nested hierarchy of features that characterize key nodes. {F}inding that {A}mborella is sister to the rest of the angiosperms has raised the question of whether it shares certain key functional trait characteristics, and plastic responses apparently widespread within the angiosperms at large. {W}ith this in mind, we test the hypothesis that local canopy openness induces plastic responses. {W}e used this variation in morphological and functional traits to estimate the pervasiveness of trait scaling and leaf and stem economics. {W}e studied the architecture of {A}mborella and how it varies under different degrees of canopy openness. {W}e analyzed the coordination of 12 leaf and stem structural and functional traits, and the association of this covariation with differing morphologies. {T}he {A}mborella habit is made up of a series of sympodial modules that vary in size and branching pattern under different canopy openness. {A}mborella stems vary from self-supporting to semi-scandent. {C}hanges in stem elongation and leaf size in {A}mborella produce distinct morphologies under different light environments. {C}orrelations were found between most leaf and stem functional traits. {S}tem tissue rigidity decreased with increasing canopy openness. {D}espite substantial modulation of leaf size and leaf mass per area by light availability, branches in different light environments had similar leaf area-stem size scaling. {T}he sympodial growth observed in {A}mborella could point to an angiosperm synapomorphy. {O}ur study provides evidence of intraspecific coordination between leaf and stem economic spectra. {T}rait variation along these spectra is likely adaptive under different light environments and is consistent with these plastic responses having been present in the angiosperm common ancestor.},
