Maple trees are identified by their 5-lobed leaves and winged fruit. Five common species are shown here. The Norway Maple differs from the Field Maple and Sycamore in that its lobes and teeth have finely pointed tips. It has a winged fruit but the wings hang down at an angle whereas those on the field Maple are flat. The Japanese Maple leaves have narrow lobes and the Silver Maple has deeply cut leaves.
Field Maple Acer campestre. The leaf has 5 main lobes. The upper side of the leaf is dark green in mid summer. The leaf edges are smooth.
Sycamore Acer pseudoplatanus.The leaf has 5 tooth-edged lobes. In comparison, the Field Maple leaves have no teeth and the Norway Maples leaves have very few.
Norway Maple Acer platanoides. The Norway Maple leaf has very fine points on the tips of its lobes and teeth.
Japanese Maple Acer palmatum. The leaf has 5 (or 7) lobes with small teeth. Leaves turn red in autumn.
