On the sea coast, in salt marshes, in various places. 



Annual. August. 



Root fibrous, downy. Stems numerous, a span long, spreading, 

 partly procumbent, leafy, round, smooth, jointed and bent. 

 Leaves of a deep glaucous green, linear, narrow, acute, single- 

 ribbed, striated, rough on the upper side and at the edges. 

 Sheaths slightly tumid, striated, smooth. Stipula short and 

 blunt. Spikes terminal, solitary, incurved, cylindrical, very 

 smooth, the closed, more or less combined, valve of the calyx so 

 exactly closing the chink of each joint, both before and after 

 flowering, as to make one even surface. The rudiment of the 

 secondary floret is but small and variable. All the glumes are 

 destitute of awns.

 weak among other grasses, as it occurs sometimes in Norfolk.
