We tested two hypotheses for how vessel evolution in angiosperms influenced xylem function. First, the transition to vessels decreased resistance to flow-often considered the driving force for their evolution. Second, the transition to vessels compromised safety from cavitation-a constraint emerging from the pit area hypothesis for vulnerability to cavitation.
