The stem is normally divided into nodes and internodes: [2] The nodes are the points of attachment for leaves and can hold one or more leaves. There are sometimes axillary buds between the stem and leaf which can grow into branches (with leaves, conifer cones, or flowers). [2] Adventitious roots (e.g. brace roots) may also be produced from the ...
a vegetative propagative body filled with starch (amylum) and located around the lower nodes of certain stonewort s. anastomose Branching and then rejoining, as with leaf venation. anastomosis A connection or fusion of two or more vein s that are normally diverging or branching, thereby forming a network. anatropous
An internodal segment (or internode) is the portion of a nerve fiber between two Nodes of Ranvier. The neurolemma or primitive sheath is not interrupted at the nodes, but passes over them as a continuous membrane.
Corms are structurally plant stems, with nodes and internodes with buds and produce adventitious roots. On the top of the corm, one or a few buds grow into shoots that produce normal leaves and flowers. Gladiolus corm, showing the formation of small cormels at the ends of short stolons
[9] [10] [11] The tuber has all the parts of a normal stem, including nodes and internodes. The nodes are the eyes and each has a leaf scar. The nodes or eyes are arranged around the tuber in a spiral fashion beginning on the end opposite the attachment point to the stolon.
In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stolon is similar to a rhizome, but stolon sprouts from an existing stem having long internodes and generating new shoots at the ends, they are often also called runners such as in the ...

These stolons from the corm of a Crocosmia are stems that emerged from axillary buds at the nodes of the tunic leaves. Stolons may have long or short internodes. The leaves along the stolon are usually very small, but in a few cases such as Stachys sylvatica are normal in size. [3] Stolons arise from the base of the plant. [4]
