Culms 10-30 cm. liigli, from hard rootstocks. Ligule and 

 sometimes slieaths eiliato; blades 3-8 em. long. Spikes 3-5 in 

 number, 3-4 cm. long. Spikelets closely imbricated; empty 

 glumes ovate-lanceolate, nearly equal, about 1.5 mm. long, mem- 

 branous except the single nerve; lloret narrowly oval, ^ mm. long; 

 floral glume comjiressed, 1-ncrved; palea longer than its glume, 

 0.7 mm. wide when spread, with the nerves close together. Stig-

S])ikelcts 1-flowered, flattened, subsessile, articulate with the 

 pedicels, arranged in rows on two sides of a triangular rachis. 

 Empty glumes compressed-keeled, unequal, acute or bristle-pointed ; 

 floral glume as long as the second empty glume or shorter, or longer 

 and wider; palea slender, longer than its glume, or equal to it, 

 almost hyaline. Stamens 3. Styles long, more or less united. 

 Grain included, but not adherent. 



Perennials, often maritime, with creeping rootstocks, and simj)lc 

 culms. Sheaths smooth; blades long and tough, soon involute; 

 si)ikes forming an erect racemose panicle, racliis extending beyond 

 the base of the upper si)ikelet. 



There are 5 or 6 species and many varieties widely dispersed 

 in America, Europe, and Africa. 



Spartina has usually been placed among Chloridea3. Bentham 

 places it in Paniceae, saying: " The spikelets, themselves containing 

 a single terminal flower, and the articulation of their pedicels, are 

 quite those of Paniceae, not of Chloridew."
