DISPERSED INTENTIONALITY. “”The world of higher plants furnishes a perfect image of dispersed intentionality in modular development or iterative growth: adaptively variable growth is uneven and involves complex branching patterns that effectively respond to sub-optimal niche conditions in order to recover the optimal niche for a given plant. Each shoot and part of root pursues its own trajectory of intentionality, reflecting the uneven distribution of resources to which it strives and, most often, contributing to the asymmetry of the whole.”
