Shape and Size

• Leaf shape refers to the lobes of a leaf. Lobes are the rounded or pointed sections of a leaf. Oak leaves are lobed. Most fruit trees do not have lobed leaves. Shape also refers to the general shape of the leaf. An oval leaf may indicate an apple tree, while a longer, thin leaf may be an orange tree. Leaf size can also help determine species. Orange leaves are 3 to 4 inches long, while papaya leaves may be 1 to 3 feet long.
  
  

Color and Texture

• Leaves can be a variety of shades of green or yellow depending on the time of year and type of tree. Apple trees tend to have a silver color on the underside and be fuzzy. Other fruit trees have a smooth texture and are the same color on both sides. Orange trees have a leaf with a leathery texture. Observe the specifics of several leaves to get an accurate view of the standard color.
  
  

Twig Arrangement

• The pattern of arrangements of leaves on each twig is an important factor in identifying trees and shrubs. Leaves are arranged alternately along the stem or directly across from each other. Trees that have similar-looking leaves may be identified by this pattern
  
  

Tips

• Utilize an identification guide with color photographs for easier identification. Observe the leaves while still on the tree whenever possible.
