MOOSEWOOD MAPLE
Acer pennsylvanicum

It is not long-lived and has small practical value, as the wood is not strong, and the sap yields only a small quantity of sugar.
The Latin name, negundo, is meaningless and its origin is unknown.
Norway Maple Acer platanoides
A tall tree, with a round head and closely fissured bark. The buds are large, round, and a dull reddish brown color. Coarse twigs and opposite leaf-scars. Distinctive characteristic is the white juice which comes after cutting off a bud.
It is particularly interesting to open the buds of this tree, and to see how carefully the leaves are protected. After removing the outer scales of the terminal bud with a knife, one discovers a pair of scales covered with soft brown hair as thick as sealskin fur and the same color. Within this warm covering there are still another pair of inner scales with fur a little darker and thicker than that of the first pair, and within these are the little leaves in embryo. In some buds one finds a tiny flower cluster instead, so small it can scarcely be seen, but perfect in every detail,—the most protected of flowers. A discovery like this makes one wonder if the dispensation of coverings is erratically bestowed, for why should we find a rugged, stalwart tree like the Norway maple with its buds luxuriously protected from the cold, while a slender, delicate tree like our moosewood has only a pair of scales for a bud-covering? There must be hidden vitality in the little moosewood, for in spring, when the leaves come out, they are as vigorous and beautiful as those of the Norway maple; perhaps, after all, it is just a matter of nationality; the Norway maple came from Europe and has kept the traditional custom of wearing warm clothing in winter, and the moosewood has lived without superfluous raiment, like an Indian in the woods.
Sugar has been made from the sap of the Norway maple, but it is produced in small quantity. The wood is easily worked, and is used in Europe for various small purposes.
Acer platanoides means platanus-like maple, and refers to an imaginary resemblance to the plane tree.
