Study Notes

Leaf Composition

A simple leaf has a continuous undivided surface.
A lobed leaf has incisions that do not reach the midrib.
A compound leaf has incisions that reach the midrib.

Leaf Lamina

The lamina is the blade of the leaf.
The size of the lamina is measured by its length and width.
The margin of the lamina can be:
- Entire (smooth)
- Serrate (toothed)
- Crenate (rounded teeth)
- Dentate (sharp teeth)
- Sinuate (wavy)
- Ciliate (hairy)

Leaf Venation

There are two main types of venation: parallel and reticulate.
Parallel venation: veins are parallel to the midrib.
Reticulate venation: veins are interconnected and form a network.
Types of reticulate venation:
- Pinnate reticulate: veins radiate from a central midrib.
- Palmate reticulate: veins radiate from a central point.
- Anastomosing venation: veins are interconnected and form a network.
