552 GBAMINILE. (GRASS FAMILY.) 



tens, Ait. )-- Salt marshes, and sancy sea-beaches, common. Auguit. (Also 

 in otic locality in S. of Eu.) 



* * Spiktkts loosely imbricated, or somewhat remote and alternate, the keels sligfitly 

 hairy or ronyhisli under a lens: spikes sessile and erect, soft; leaves, rhachis, frc. 

 very smooth : culm, $-c. rather succulent. 



4. S. strict;!, Roth. (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 1 -nerved, a little longer than the palese. Salt 

 marshes, Pennsylvania, &c. (Muhl.) (Eu.) 



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

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

 on the coast. 



Var. alterui flora. (S. alterniflora, Loist/. Dactylis cynosuroidcs, var, 

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

 lapping, the rhachis 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 palese, the one or two uppermost 

 of empty awnlcss paleae : the perfect flower intermediate in position ; its paleaa 

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

 ciliate towards the base, 3-nerved. Squamula3 2. Stamens 3. Stigmas plu- 

 mose. (Name Krei/ioi/, a small comb, from the pectinate appearance of the spike. ) 



1. C. American!!!!!, Spreng. Culm (3 -4 high) simple, pubescent 

 or rough ish ; larger glume warty-glandular outside and conspicuously awned. 

 1|. (Monocera aromatica, EU.) Wet pine barrens, S. Virginia and southward. 



- Taste very pungent. 



18. BOUTEL.OIIA, Lagasca (1805). MUSKET-GRASS. 



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

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

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

 Perfect flower with the 3-ncrvcd lower palea 3-toothed or cleft at the apex, the 

 2-uerved upper palea 2-toothcd, the teeth, at least of the former, pointed or subu- 

 late-nwnc. I. Stamens .'3 : anthers orange-colored or red. Rudimentary flowers 

 mostly 1 -3-awned. Spikes solitary, raeenied, or spiked ; the rhachis somewhat 

 extended bryond the spikelets. (Named for Claudius Boutdou, a Spanish writer 

 upon floriculture and agriculture )
