Дуб болотный каштановый (Quercus michauxii)

Species of oak tree

Quercus michauxii, the swamp chestnut oak, is a species of oak in the white oak section Quercus section Quercus in the beech family. It is native to bottomlands and wetlands in the southeastern and midwestern United States, in coastal states from New Jersey to Texas, inland primarily in the Mississippi–Ohio Valley as far as Oklahoma, Missouri, Illinois, and Indiana.

The leaves of the swamp chestnut oak are simple (not compound), long and broad, with 15–20 lobe like, rounded simple teeth on each side, similar to those of chestnut oak and chinkapin oak (Quercus muehlenbergii), although they generally do not achieve the more slender form that the leaves of those trees may exhibit at times. The leaves turn red in autumn. The fruit is an acorn long and broad, borne on a 2–3 cm peduncle, maturing in the fall, about 6 months after pollination. The tree only bears heavy acorn crops at intervals of several years. although sometimes that name is declared to be of uncertain position, unassignable to either species, with the chestnut oak then called Q. montana, as in the Flora of North America.

The acorns of the swamp chestnut oak are eaten by generalist species like chipmunks, squirrels, white tail deer, wild hogs, and black bears. They are also readily eaten by cattle,

The wood of the swamp chestnut oak is similar to, and usually marketed mixed with, that of other white oaks. Swamp chestnut oak is also called basket oak, since the wood is easily split into long, thin, flexible strips excellent for basket weaving. The swamp chestnut oak's acorns are large, relatively sweet, and edible.
