According to Oregon State's Department of Horticulture, leaves are a common way of identifying plants. Leaves may be broad or narrow, simple or compound, and lobed or toothed. It is important, however, to note one of the broader details: a leaf's overall shape.

This leaf has a very narrow shape with almost parallel sides. It comes to a point at the end. This group includes sword-shaped leaves (long and needle-shaped). Most grass blades are linear shaped. A linear leaf can be simple; that is, undivided with only one main section.

This type of blade is similar to the linear leaf but is wider in the center. It is still longer than it is broad and tapers to a point at the end. Most lanceolate leaves are compound leaves and are divided by a septum in the center. Alpinia evergreens have lanceolate leaves, as do daffodils.

A cordate is so named for its heart-shaped blade. The point of the heart may originate at the top or bottom of the leaf. The flowering perennial, cyclamen, has this type of leaf.
