Axis   [ Botany ]
Adjective: Axial

Dictionary of botanic terminology - index of names

  In geometry an axis is the central line of a body or part thereof, especially the imaginary line around which rotation takes place.

In botany an axis is the main stem of a plant, or a central line of symmetry, development, or growth around which plant organs or parts are arranged both in plan and in elevation.


The axis of a plant runs through the middle of it, e.g., the central stem of a plant to which organs or parts are attached,  the primary root or the stalk (rachis) of a compound leaf or of an inflorescence.
