Missouri Leaf Identification

Identifying a single leaf can lead you down a variety of paths. Some trees have leaflets, which make up a larger leaf, like the ash tree. This can make it difficult to determine the origin of the leaf. Missouri trees include most of the common trees in North America, like the maple and elder. Identifying a plant by leaf found in Missouri requires the help of a good leaf identification book, as it's nearly impossible for a beginner nature enthusiast to know every Missouri plant, tree and bush by the shape of its leaves.

Instructions

- 1
  Look around the area in which you found the leaf to find a match. Nearly all green growing things have leaves. If you narrow it to a tree, flower, or bush, then you can identify the leaf faster and with less hassle. If you find the origin, note the bark texture and any other identifying characteristics.
- 2
  Determine whether the leaves are simple or compound. Simple leaves originate directly from the branch, while compound leaves sprout from a slender twig off the branch.
- 3
  Take a picture of the leaf and put into a waterproof bag for further analysis later.
- 4
  Decide whether the plant is coniferous or deciduous. Coniferous plants have needle-like leaves, while deciduous have large flat leaves.
- 5
  Look closer at the leaf. Determine whether it has scales or serrated edges. Note the shape. Count the number of needles or leaflets in a leaf.
- 6
  Note the color of the leaf. Even if the leaf turned colors before dropping in the fall, the red, yellow, purple, or orange color can help identify the leaf.
- 7
  Open a book on Missouri tree or plant identification to the section detailing trees with the characteristics gathered. Use the information and the picture or actual leaf to determine the leaf origin.
