[March, 



densely flowered ; spikelets 3- to 7-flo\vercd, 25 lo oO nun. long ; glumes 

 and lemmas pointed, covered with short, soft pubescence, sometimes 

 glaucous. 



The plants of this species are reed-like. They are found in sandy 

 places along the northern Atlantic coast and the shores of the Great 

 Lakes. The only specimen seen by the writer was found too late to 

 include a figure of the spikelet, but it is very easily recognized and 

 not likely to be confused with any of the other species.
