Acer platanoides (Norway maple): Leaves
		The leaves are simple, opposite, 2.5 to 6 inches long and 4 to 7 inches across, with 5 to 7 bristle-tipped lobes. The margins of the lobes are smooth, or with 1 or 2 pairs of sharp, bristle-tipped teeth per lobe. The leaf surface is smooth, except for tufts of hairs on the lower surface in the vein axils. The petioles are reddish and 3 to 4 inches long, with a milky sap. The fall leaves are less attractive than those of the sugar maple (A. saccharum), remaining green or turning yellow.
