description

The Calabrian maple grows as a tree and usually reaches heights of 12 to 15 meters, in exceptional cases up to 20 meters. The tree crown is tightly upright, columnar or pyramidal (subspecies feature). The bark of the branches is blue-green frosted (subspecies characteristic), rarely also purple-brown. The bark shows whitish stripes on older branches.

The constantly against arranged on the branches leaves are stalked 6 to 10 centimeters long. The petiole carries milky sap. The simple leaf blade is 12 to 15 centimeters wide and just as long, heart-shaped at the base, five-lobed with triangular, long, pointed lobes with entire margins. The leaf margin is entire to wavy (subspecies characteristic). The leaf lobes point - characteristic of this subspecies - to the front. The upper side of the spade is glossy dark green, the underside more blue-green. The upper side is hairless, the nerve axils of the underside of the leaf usually have hair. The autumn color is golden yellow.

Short trugdolige inflorescences are formed during the flowering period in May . The pedicels and calyx are softly hairy. The yellow-green, five-fold flowers have a diameter of about 5 millimeters and appear at the same time as the foliage.

The split fruits have almost horizontally spread, 2 to 3 centimeters long wings and flat seeds. They are also often incompletely pollinated on site.
