50. jEscuIus glabra, Willd. 

 Ohio Buckeye. Fetid Buckeye. 



Western slopes of the Alleghany Mountains from Pennsylvania to 

 northern Alabama, and westward through southern Michigan (rare) to 

 southern Iowa, eastern Kansas, and the Indian Territory. 



A small tree, 8 to 15 metres in height, with a trunk 0.00 to 0.G0 

 metre in diameter ; rich soil along streams and bottom-lands ; reaching its 

 greatest development in the high valleys of the southern Alleghany 

 Mountains. 



Wood light, soft, not strong, close-grained, compact, difficult to split, 

 often blemished by dark lines of decay ; medullary rays obscure ; color 

 white, the sap-wood a little darker ; largely used, in common with that of 

 the other species of the genus, in the manufacture of wooden-ware, artificial 

 limbs, paper pulp, wooden hats, less commonly for the bearings of shaft- 

 ing and machinery, and occasionally manufactured into lumber. 



The bark of the allied old-world species JE. Hi ppocastanum has been 

 found efficacious as a substitute for cinchona bark in the treatment of 

 intermittent fevers, and similar properties may be looked for in the bark 

 of the North American species of this genus.
