Acer platanoides
Norway maple

Sapindaceae (soapberry family)
Europe
Acer platanoides leaf and samara. From: Howard E. McMinn & Evelyn Maino, An Illustrated Manual of Pacific Coast Trees

Native to a vast region extending from southern Norway to the Pyrenees and from the Caucasus to the Urals, Norway maple has been introduced all across the United States. The five-lobed leaves are about 6 inches across and are placed oppositely on stalks up to 5 inches long. The sap in the leaf stalks is milky and sweet. Before the leaves appear, clusters of small yellowish green flowers make a display. Keys about 2 inches across quickly develop. A brilliant yellow display occurs in late autumn. Pliny tells us that the waxed tablets used in Roman times as note pads were of maple wood. Two trees south of Cantor Center and one near the southwest corner of the Main Quad are possibly ‘Schwedleri’ and/or ‘Reitenbachii’. My friend Margot Pratt shows kids how to wear a samara like spectacles, or break one in half, remove the seed, and stick it on like a rhino.

Name derivation: Acer – Latin for maple; platanoides – like Platanus.
