Arboreal Structures

This form of communication (or "transmission" if we want to avoid the connotations of "commonality" in the former term) is what Deleuze and Guittari later expressed as "rhizomic". This is opposed to the "arboreal" (tree-like) form, where parts are related to each other only through their relationship to a common root, and whose importance is measured according to their distance from that root. In contrast, the rhizome spreads horizontally through leaps where each germination marks a new root system and one cannot assign an origin or end-point.
