Iris rhizome

In botany, a rhizome is a horizontal stem of a plant that is usually found underground and often sends out roots and shoots from its nodes. Good examples of plants with underground rhizomes include medicinally important ginger and turmeric and the economically damaging weeds Johnson grass, bermuda grass and purple nutsedge. The spreading stems of ferns are also rhizomes. Some plants have rhizomes that grow above ground or that sit at the soil surface including some Iris species. Rhizomes may also be referred to as creeping rootstalks, or rootstocks. A stolon is similar to a rhizome, but instead of being the main stem of the plant, which is what a rhizome is, a stolon sprouts from an existing stem and has long internodes and generates new shoots at the end. A good example of a plant that grows with stolons is strawberry. Rhizomes typically have short internodes; they send out roots from the bottom of the nodes and new vertically growing shoots from the top of the nodes. Rhizome may refer to one of the following Rhizome, a usually-underground, horizontal stem of a plant that often sends out roots and shoots from its nodes. ...

Gilles Deleuze / Félix Guattari _Rhizome_ (2046 words)
Let us summarize the principal characteristics of a rhizome: unlike trees or their roots, the rhizome connects any point to any other point, and its traits are not necessarily linked to traits of the same nature; it brings into play very different regimes of signs, and even nonsign states.
Unlike the tree, the rhizome is not the object of reproduction: neither external reproduction as image-tree nor internal reproduction as tree-structure.
What is at question in the rhizome is a relation to sexuality—but also to the animal, the vegetal, the world, politics, the book, things natural and artificial—that is totally different from the arborescent relation: all manner of “becomings.
