Buckeye
the sweet horse-chestnut. It is a fine tall forest tree of the soapberry family, akin to the maple and box elder. The leaf resembles that of the chestnut. The fruit is a leathery pod containing a large seed, or rather nut, with a shiny coat and a round, pale scar. The nut resembles the soft, lustrous eye of the Virginia deer, whence the name. The buck-eye is found in rich woods from the Ohio Valley southward. Ohio has been nicknamed the "Buckeye State." In addition to the Ohio buckeye, there are others, as the red buckeye, the shrubby sweet buckeye, and the white buckeye of the mountains. There are several similar species in Asia.
