The veins of a bramble leaf. The veins are the vascular tissue of the leaf and are located in the spongy layer of the mesophyll. The pattern of the veins is called venation. In angiosperms the venation is typically parallel in monocotyledons and forms an interconnecting network in broad-leaved plants.
A primary vein, also known as the midrib, is the main vascular structure running through the center of a leaf. [1] The primary vein is crucial for the leaf’s efficiency in photosynthesis and overall health, as it ensures the proper flow of materials and structural integrity.
Acrodromous – the veins run parallel to the leaf edge and fuse at the leaf tip. Actinodromous – the main veins of a leaf radiate from the tip of the petiole. Brochidodromous – the veins turn away from the leaf edge to join the next higher vein. Campylodromous – secondary veins diverge at the base of the lamina and rejoin at the tip ...

Aphids and leaf hoppers feed off of these sugars by tapping into the phloem. This is why aphids and leaf hoppers are typically found on the underside of a leaf rather than on the top. The position of vascular bundles relative to each other may vary considerably: see stele. The vascular bundle are depend on size of veins
