Trees. 258 The Birches. leaf-stalks are i to cm. long. The flowers open in May. The clustered staminate cat- kins are 6 cm. long or longer, their scales broadly ovate and bluntish. The ripe pistillate catkins are oblong-cylindric, 2 to 3 cm. long, very short-stalked or stalkless, their scales 4 to 6 mm. long, more or less hairy, nearly or quite as wide as long, 3-lobed above the middle, the wedge-shaped part below the lobes very short, the edges sparingly long-hairy; the nut is nar- rowly obovate or oblong, 2 to 3 mm. long. It is also called Gray birch and Water birch. 15. YELLOW BIRCH —Betulalutea F. A. Michaux Fig. 216. — Southern Yellow Birch. The Yellow birch, also called Gray birch, is a forest tree, ranging from Newfoimdlcind to Manitoba, south to Massachusetts, Pennsylvania, and Wisconsin. It is a very large tree, reaching a maximum height of about 30 meters, with a trunk i to meters in diameter. The bark of young and middle-aged trunks is usually silvery gray or yellow- ish, and is either close and furrowed or peels off freely in very thin layers; on old trunks, especially near their bases, it is rough, reddish brown, fissured, and often cm. thick; trees of the same size standing side by side often exhibit the bark either close or peeling, so that the age or size of the trunk is not absolutely correlated with the character of the bark. The young twigs are long-hairy and green, becoming brown or orange-brown, smooth and shining, finally silvery-gray. The pointed buds are about 6 mm. long and somewhat hairy. The leaves are ovate or oblong-ovate, pointed, often long-pointed, sharply simply or doubly toothed, 7 to 12 cm. long, rounded, somewhat narrowed or rarely cordate at the base; they are long-hairy when young, dark green and smooth on the upper surface, paler green and hairy o
