The chestnut oak is one of the most desirable kinds of trees to plant in parks. It is symmetrical, with handsome bark and foliage. The leaves turn yellow and keep their fine texture through the season. The acorn is one of the handsomest and largest, and squirrels are delighted with its sweet kernel.
The Mississippi Valley Chestnut Oak
Q. acuminata, Sarg.
In the Mississippi Valley the chestnut oak is Q. acuminata, Sarg., with a more slender and more finely-toothed leaf that bears a very close resemblance to that of the chestnut. The foliage mass is brilliant, yellow-green, each leaf with a pale lining, and hung on a flexible stem. "Yellow oak" is another name, earned again when in autumn the leaves turn to orange shades mingled with red.
On the Wabash River banks these trees surpass one hundred feet in height and three feet in diameter. The base of the trunk is often buttressed. Back from the rich bottom lands, on limestone and flinty ridges, where water is scarce, these trees are stunted. In parks they are handsome, and very desirable. The bark is silvery white, tinged with brown, and rarely exceeds one half an inch in thickness.
The Swamp White Oak
Q. platanoides, Sudw.
The swamp white oak loves to stand in wet ground, sometimes even in actual swamps. Its small branches shed their bark like the buttonwood, the flakes curling back and showing the bright green under layer. On the trunk the bark is thick, and broken irregularly into broad, flat ridges coated with close, gray-brown scales often tinged with red.
In its youth the swamp white oak is comely and symmetrical, its untidy moulting habit concealed by the abundant foliage. One botanist calls this species bicolor, because the polished yellow-green upper surfaces contrast so pleasantly with the white scurf that lines each leaf throughout the summer. Yellow is the autumn color. Never a hint of red warms this oak of the swamps, even when planted as a street or park tree in well-drained ground.
