1. ^sculus glabra Willdenow. Buckeye. Plate 114. Branch- 

 lets at first covered with hairs which soon disappear, orange brown 

 becoming a reddish-brown; terminal bud sharp-pointed, about 1.5 

 cm. {}/2 inch) long, scales of bud nearly triangular; flowers appear 

 in May, pale yellow green. 



Distribution. Pennsylvania to Iowa, south to Alabama and west 

 to Kansas. Probably native to every county of Indiana, although 

 scarce at present because it has been destroyed on account of the 

 poisonous character of its fruit. It is rare in the extreme northern, 

 northwestern and southwestern counties. In the other parts of 

 the State it is locally frequent in moist rich soil, usually along 

 streams. In the greater part of the State it is frequently associated 

 with sugar maple and beech.

 cock, Henry, Howard, Jennings, Madison, Marion, Montgomery,

Economic uses. Wood white, soft, not strong, rather tough. 

 Used for pulp. The fact that the wood is of httle commercial 

 value and that the fruit is poisonous to stock has caused it to be 

 cut until at present only isolated trees remain. For ornamental 

 use it has been supplanted by the horse-chestnut.
