The question of circumstance ...
What is an internode?
Ivy leaves are arranged alternately on the stem, once on one side, once on the other, and so on. The place where the leaf attaches to the stem is called the node. The space between two consecutive nodes is called theinternode.
The distance between nodes varies greatly from one species and cultivar to another. Node spacing is therefore often a distinctive characteristic of varieties.
Ivy with short internodes is compact, well-filled with leaves. They often form thick mats. In contrast, ivy with long internodes has sparser leaves on much longer stems. These ivies form a less dense cover, which can be an advantage or a disadvantage depending on the intended purpose and use.

Ivy in literature
“In the silence of the cloisters, the ivy stretched out its arms like a silent prayer towards the sky.”
