    • Abstract

       

      The high order foliar vein sheathing of 40 species representing 6 genera of Cunoniaceae was examined. The type, orientation, distribution, and proportion of the sheathing elements around the veinlet, including the terminal cells, are variable and useful for generic circumscription and subdivision. Terminal cells are tracheoidal or sclereidal types. A general trend towards the formation of specialized sclerenchymatous terminal elements is supported.
