The blade is roundish, palmately lobed, large, 10-20 cm (3,93 - 7,87 in) long and about the same width, dark green on the upper surface and gray-green underneath, blunt, slightly hairy at the nerve angles on the underside. The lobes, 5 in number, are ovate, pointed at the end, separated by a wedge-shaped indentation, irregularly toothed or filed on the edges. The toothed edges are flatter and softer than in common maple.
