foot-hills and alonj;' the crests of ridges and bluffs so frequent in 

 the eastern part of the State. This species ^^rows to the hcij^ht 

 of two or thrc*e feet, is soft-hairy all over, and is of a much 

 stouter habit than Danthonia compressa, but it does not appear 

 to form a sod, and our attempts at cultivating^ it have been 

 unsuccessful. 



Danthonia spicata, />V^/^t' — Wild Oat-s^-raj-s, White-top, Old Fo^, 

 june-*;rass. Poverty-grass. 

 DantJionia spicata is common in dry, thin soils, and its presence 

 is usually indicative of impoverished lands. It resembles very 

 much Pantlwnia comprcssa, but does not usually grow so tall, and 

 its leaves are much shorter and more curly. It is a grass of no 

 agricultural value.

We have seen this grass on Roane Mountain and on Lookout 

 Mountain, and probably it may be found upon all the mountains 

 of East Tennessee. The slender stems are one to three feet high, 

 and the leaves, which are chiefly at the base, are very slender, 

 almost thread-like. It is a grass of no agricultural value.
