What is the term used to describe the arrangement of veins in the lamina of a leaf?

Step-by-step solution

The arrangement of veins and the veinlets in the lamina of leaf is termed as venation. When the veinlets form a network, the venation is termed as reticulate (Figure 5.4 b). When the veins run parallel to each other within a lamina, the venation is termed as parallel (Figure 5.4 c). Leaves of dicotyledonous plants generally possess reticulate venation, while parallel venation is the characteristic of most monocotyledons.
