tens, Ait.) — Salt marshes, and sandy sea-beaehes, common. August. (Also 

 in one locality in S. of Eu.) 



* * Spikdets loosely imbricated, or somewhat remote and alternate, the keels sKyhily 

 hairy or roughish under a lens ; spikes sessile and erect, soft ; leaves, rhachis, ^c. 

 very smooth : cvltn, Sfc. raiher succulent. 



4. S. Stricta, Koth. (Salt Maesh-Geass.) Culm l°-3° high, leafy 

 to the top; loaves 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 palea;. — Salt 

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



Var. g'lahra, Muhl. (S. glabra, MjA/., partly.) Culm and leaves mostly 

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

 on the coast. 



Var. alternifldra. (S. altemiflora, ioi'seZ. Dactylis cynosuroides, var., 

 L.) Spikes more slender (3' -5' long), and the spikelets remotish, 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) : bthei-wise as in the preceding form, into which it passes. — Com- 

 mon with the last. — Odor strong and rancid. 



17. CTEMIUM, Panzer. Toothache-Geass. 



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, beaiinga stout recni-ved 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 a\vnless palese : the perfect flower intermediate in position ; its palese 

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

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

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



1. C Americaiium, Spreng. Culm (3°-4°high) simple, pubescent 

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

 M (Monocera aromatica. Ell.) — Wet pine barrens, S. Virginia and southward. 

 — Taste very pungent. 



18. BOVTELiOlJA, 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 witli the 3-nerved lower palea 3-toothed or cleft at the apex, the 

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

 late-awncd. Stamens 3 : anthers orange-colored or red. Rudimentary flowers 

 mostly 1 -3-awacd. Spikes solitaiy. racemcd, or spiked ; the rhachis somewliat 

 extended beyond the spikelets. (Named for Claudius Boutehu, a Spanish writer 

 upon floriculture and agriculture.)
