A study refers to the venation patterns of Cordia myxa L. species. Venation systems have been classified with the
design for each order and in the present study, the venation is pinnate and the type of the first-order veins was brochidodromous,
cascade type for the second-order veins and the type of third order veins was lattice and percurrent. The areoles are variable in
size, they are triangular or polygonal.Studied of venation is necessary for leaf architecture, because which associated with the
development of lamina and patterns formed by groups of venation designs.
