internode

[′in·tər‚nōd]
(biology)
The interval between two nodes, as on a stem or along a nerve fiber.

Internode

 

the area of a stem or shoot between two neighboring nodes—the sites of leaf attachment. When there is close placement of leaves, as in the basal rosettes of dandelions, daisies, and plantains, the internodes are greatly abbreviated and almost unnoticeable. In young shoots the internodes are short and the nodes are close together; as the stem or shoot grows, the internodes become longer. The growth of the internodes is effected by the activity of the meristem, which is located either at the base of the internode (in the Gramineae and Caryophyllaceae) or in its upper part (Ranunculus and Plantago).
