The flowers are dioecious, so far as they are known, and appear before the leaves very early in the season. The samaras are larger than those of the Red maple, being to cm. long, nearly erect or somewhat divergent, with a wing I to 2 cm. in width. The persistently woolly leaves and large fruit seem to mark this southern tree as specifically different from the northern Red maple. The wood of Drummond's maple is very similar to that of the Red Fig. 600. — Drummond's Maple. 13- SUGAR MAPLE—Acer Saccharum MarshaU Acer sactharinum Wangenheim, not Linnsus The Sugar maple prefers rocky uplands, and is often called Rock maple, Sugar tree, and Hard maple; it is a grand tree, sometimes attaining a height of 40 meters, with a trunk diameter of meters, perfect specimens appearing when in leaf, like great round domes. It ranges from Newfoundland to Georgia, but south of Maryland is rare near the coast, and extends westward to Manitoba, Nebraska, and Texas. The bark of old trunks is channelled, brown and scaly, that of young ones light brown and smooth. The young twigs are smooth and green, but soon become brown or orange- brown; the inner bud-scales are silky, becom- ing 2 to 4 cm. long in unfolding, and light yel- low. The long-stalked spreading leaves are rather thin in texture, dark green above, paler green or quite glaucous beneath, hairy on the under side when young, but nearly or quite smooth when mature; they are orbicular in out- FiG.
