Leaf Identification
The leaves of the Sugar Maple are simple (no leaflets), oppositely arranged on the stem, palmately veined, and lobed. Technically, the Sugar Maple has 5 lobes, although the two basal lobes are not as large as the others, but they each have a major vein along their length. The upper lobes are set at ~45 degree angles from each other with deep sinuses, and are pointed at the tip, often with multiple tips on one lobe. The leaf is green and turns a variety of autumn hues in the fall.
