Leaf Veins: Impressed

Veins are located below the plane of the surface and are often exposed on the lower surface. Tissue near veins often appears to pucker, giving veins a sunken or embossed appearance.

The photo of the Hardy Rubber Tree is the least impressed of the three samples here. All three of these examples are also pinnate.
