22. SPARTINA Schreb.; Gmel. Syst. 123. 1791. 



Perennial glabrous grasses, with long horizontal rootstocks, flat or in- 

 volute leaves, and an inflorescence of one-sided spreading or erect alternate 

 spikes. Spikelets 1-flowered, narrow, deciduous, borne in two rows on the 

 rachis, articulated with the very short pedicels below the scales. Scales 3 ; the 

 two outer empty, keeled, very unequal; the third subtending a perfect flower, 

 keeled, equalling or shorter than the second; palet often longer than its scale, 

 2-nerved. Stamens 3. Styles filiform, elongated. Stigmas filiform, papillose 

 or shortly plumose. Grain free. [Greek, referring to the cord-like leaves of 

 some species.] About 7 species, widely distributed in saline soil, a few in 

 fresh- water marshes. Type species: Spartina Schreberi Gmel.
