“In botany, a rhizome (from Greek: ῥίζωμα, rhizoma, “root-stalk”) is a characteristically horizontal stem of a plant that is usually found underground, often sending out roots and shoots from its nodes. Rhizomes may also be referred to as creeping rootstalks, or rootstocks.”

“The rhizome itself assumes very diverse forms, from ramified surface extension in all directions to concretion into bulbs and tubers. When rats swarm over each other. The rhizome includes the best and the worst: potato and couchgrass, or the weed. Animal and plant, couchgrass is crabgrass. We get the distinct feeling that we will convince no one unless we enumerate certain approximate characteristics of the rhizome. “(Deleuze)
