Leaf Structure

In dicots the veins branch continuously into a fine network or paftern of veins refened to as netted venation while monocots have less branching with several main veins running the length of the blade. This longitudinal pattern of veins is parallel venation. Netted venation is FIGURE 1 Simple Pinnately Compound ...

You will note that the leaflets are attached to lateral veins branching from the rachis thus resulting in a leaf which is two times (bi-pinnately) compound. tip petiole leaflet Figure 3: Pinnately-Compound Leaf rachis tip leaflet rachis petiole Figure 4: Bi-pinnately Compound Leaf

Collecting and Exhibiting Tree Leaves

Consult the official reference book, Forest Trees of Oklahoma by E.L. Little, Jr., for examples of typical leaf size, shape, and types (simple, palmately compound, pinnately compound, bipinnately compound, and needle, scale, or awl).
