Details of reticulate venation

Blind terminal veins inside of areoles

The network that is formed by minor veins varies in size and shape. Accordingly, the veins subdivide the lamina surface into small areas called areoles (sing. = areole) delineated by the thinnest veins. Aeroles may contain one or more blind terminal veins which sometimes may have druses at the tip (not shown here).
