Root annual, consisting of woolly fibres. Cubns numerous, from 

 a span to a foot or more in height, erect, very slender, pubes- 

 cent and somewhat quadrangular above. Leaves an inch long, 

 erect, involute. Sheaths slightly pubescent. Sti/iutc short, 

 truncate, often toothed. Panicle about 2 inches long, racemose 

 or spiked ; branches simple ; the lower ones geminate, some- 

 times a little expanding. Calyx- deciduous; glumes acute. 

 Inferior valve of the corolla very narrow, without nerves, 

 rounded on the back, (not carinate ;) sides margined, involute 

 towards the extremity, and produced into a bristle two-thirds 

 the length of the valve ; superior valve very acute, shorter 

 than the other, strongly margined, puncticulate. Seed linear, 

 with a deep groove on one side the whole length. 

 Had. In dry sandy soils, and on stony hills ; common. June. 

 I have observed a Festuca growing in abundance on the 

 sea-coast of Long-Kland, which may be a variety of the last. 

 It is, however, much taller, the panicle somewhat spreading, 

 the leaves narrow, but flat, and the stipule nearly obsolete. I 

 have also found the same plant on the side of a sand-hill near 

 Flushing, Long-Island, and Dr. Bigelorj has sent me speci- 

 mens collected near Boston, Massachusetts,
