Dictionary of botanic terminology - index of names

The midvein or primary vein is the main or central vein of a leaf from which arise the secondary or lateral veins.

More frequently called midrib or stem of the leaf, especially when it is prominently raised or depressed, the midvein is the main or central vein of a leaf from which arise the secondary or lateral veins. It is usually continuous with the petiole and is often raised above the lamina (the leaf blade). On a compound leaf, the midrib (rachis) extends from the first set of leaflets (where the petiole ends) to the end of the leaf.
