Reticulate Venation: When veins form a network, it is called reticulate venation. It is further divided into the following types:

  • Pinnate or Unicostate Reticulate Venation: There is a single prominent vein called midrib which extends from the base to the apex of the lamina. The midrib gives rise to lateral veins along its length. For example, mango, peepal, etc.
  • Palmate or Multicostate Reticulate Venation: A number of prominent veins arise from the tip of the petiole and reach up to the apex or margin of the apex. For example, Ziziphus, grapevine, etc.
