4. S. Strict:*, Koth. (SALT MARSH-GRASS.) Culm l-3 high, leafy 

 to the top ; leaves convolute, narrow; spikes few (2-4), the rhachis slightly 

 projecting at the summit beyond the crowded or imbricated spikelets ; glumes 

 acute, very unequal, the larger I -nerved, a little longer than the palcie. Salt 

 marshes, Pennsylvania, e. (MuJil.) (Eu.) 



Var. gJMtra, Muhl. (S. glabra, HfuhL, partly.) Culm and leaves mostly 

 longer; spikes 5-12 (2' -3' long), the spikelets imbricate-crowded. Common 

 on the coast. 



Var. alteriliflora. (S. altcrniflorn, Loiwl. Dactylis cynosuroidcs, var , 

 L.) Spikes more slender (3' -5' long), and the spikelets remotish, barely over- 

 lapping, the rhaehis continued into a more conspicuous bract-like appendage: 

 larger glume indistinctly 5-nerved (not so evidently as in the Eu. and Trop. 

 Amer. plant) : otherwise as in the preceding form, into which it passes. Com- 

 mon with the last. Odor strong and rancid. 



17. CTENIUM, Panzer. TOOTHACHE-GRASS. 



Spikelets densely imbricated in two rows on one side of a flat arcuate-curved 

 rhachis, forming a solitary terminal spike. Glumes persistent; the lower one 

 (interior) much smaller; the other concave below, bearing a stout recurved awn, 

 like a horn, on the middle of the back. Flowers 4-6, all but one neutral ; the 

 one or two lower consisting of empty awned paleai, the one or two uppermost 

 of empty awnless palcac : the perfect flower intermediate in position ; its palcae 

 membranaceous, the lower awned or mucronate below the apex and densely 

 ciliate towards the base, 3-ncrved. Squamulse 2. Stamens 3. Stigmas plu- 

 mose. (Name Kreviov. a small comb, from the pectinate appearance of the spike. )

18. BOIITEL.OIJA, Lagasca (1805). MUSKET-GRASS. 



Spikelets crowded and closely sessile in 2 rows on one side of a flattened 

 rhacliis, comprising one perfect flower below and one or, more sterile (mostly 

 neutral) or rudimentary flowers. Glumes concave-keeled, the lower OIK- shorter. 

 IVrf 'ct flower with the 3-nerved lower palea 3-toothed or cleft at the apex, tho 

 2-nerved upper palea 2-toothed, the teeth, at least of the former, pointed or suhti- 

 late-awni'd. Stamens ;? : anthers orange-colored or red. IJudimentavy (lowers 

 mostly 1 -.Tawni'd. Spikes solitary, racemed, or spiked ; the rhachis somewhat
