Tree Leaf IdentifierMaple Leaf Identification: Recognize Common Maple Leaves
What features help identify a maple leaf?
Many maples have a simple leaf blade with several lobes spreading from its base, opposite leaves on the twig, and paired winged seeds. Check these features together. Japanese maple (Acer palmatum) usually has five to nine lobes, but leaf shape and color vary by cultivar.

Many maples have palmately lobed leaves: several main veins spread from where the leaf stalk meets the blade. Their paired winged seeds, called samaras, are another strong clue.
Count the main lobes
Many maple leaves show three to five main lobes, but the depth and sharpness of the cuts varies by species.
Inspect the edge
The lobe edge may be smooth, coarsely toothed, or finely serrated. Use a close-up photo if the margin is hard to see.
Find paired samaras
Paired winged seeds are characteristic of maples and help separate them from trees with superficially similar leaves.
Use a photo as a starting point
Capture the front and back of the leaf in natural light, include the leaf stem when possible, and photograph bark, fruit, or buds too. Then compare several features before making a final identification.
Worked name check: which sycamore do you mean?
A broad, lobed leaf and the name “sycamore” do not define one species worldwide. Work through the name and the twig before comparing a photograph.
- Resolve the name: this library’s sycamore profile describes sycamore maple, Acer pseudoplatanus. American sycamore is Platanus occidentalis.
- Inspect the twig: opposite leaf attachment supports a maple; alternate attachment supports American sycamore in this comparison. Check multiple nodes because missing leaves can obscure the pattern.
- Check the fruit: paired winged seeds support a maple; hanging round fruit heads support American sycamore. The photographs here show maples, so they cannot confirm an American sycamore on their own.
- Record uncertainty: if you only have a detached leaf, save the candidate names and return for twig or fruit photographs.

Compare two maples in the library
Japanese maple usually has five to nine lobes and a finely toothed edge. Sycamore maple has broader five-lobed leaves. Use the photographs as examples, then check the twig and the plant label when identifying an ornamental tree.
Why the name sycamore can mislead
A UK guide may call Acer pseudoplatanus simply sycamore. A North American guide may use the same name for a plane tree. The comparison guide below separates these meanings and gives clues you can check on the twig and fruit.
Keep cultivar variation in mind
Garden maples can look different from a single reference photograph. Compare shape, twig arrangement, and fruit before using leaf color as a clue. If the tree has a nursery label, include its cultivar name in your notes.
