Generally, the parallel venation is found in

Monocotyledons.

Venation 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.

When the veins run parallel to each other within a lamina the venation is termed as parallel. Leaves of dicotyledonous plants generally possess reticulate venation, while parallel venation is the characteristic of most monocotyledons in reticulate venation vein form network
