A coast-grass, far-creeping, sometimes very depressed ; 

 stems always short and often quite dwarfed ; leaves in

 clusters, occasionally long-stalked, the rhachis far ex- 

 tended beyond the spikelets, particularly those of the 

 pistillate plant ; bracts few to each spikelet, the lower 

 sometimes as long as the others ; stigmas elongated ; fruit 

 loosely enclosed within the supporting and covering bract.
