NORWAY MAPLE (Acer platanoides). A round-headed dense tree, very quick and vigorous of growth in the United States, with dark green, smooth broad leaves, 5-lobed, re motely toothed, with milky sap, scarcely paler beneath, 5 to 6 inches long and broad, turning clear yellow before falling. Flowers yellow-green, in flat clusters, after leaves, in May, fol lowed by pairs of thin, broad-winged keys spreading to almost opposite position, and joining in a straight line between the seed ends. Red-leaved varieties are also much planted.
One of the best maples for avenue planting and for home grounds.
