Spikelets plainly 3-flowered, open-panicled ; the flowers all with 2 paleae the 

 two lower (lateral) flowers staminate only, 3-androus, sessile, often awned on the 

 middle of the back or near the tip ; the uppermost (middle) one perfect, short- 

 pedicelled, scarcely as long as the others, 2-androus, awnless. Glumes equalling 

 or exceeding the spikelet, scarious; paleae chartaceous. Leaves linear or lan- 

 ceolate; flat. (Name composed of tepos, sacred, and x^oa, grass ; these sweet- 

 scented Grasses being strewn before the church-doors on saints' days, in the North

1. H. borealis, Roem. & Schultes. (VANILLA or SENECA GRASS.) 

 Panicle somewhat one-sided, pyramidal (2' - 5' long) ; peduncles smooth ; 

 staminate flowers with the lower palea mucronate or bristle-pointed at or near 

 the tip ; rootstock creeping. U. (Holcus odoratus, L.) Moist meadows, Mass. 

 to Wisconsin, and northward, chiefly near the coast and along the Lakes. May. 

 Culm l-2 high, with short lanceolate leaves. Spikelets chestnut-color; 

 the sterile flowers strongly hairy-fringed on the margins, and the fertile one at 

 the tip. (Eu.) 



2. H. alpina, Roem. & Schultes. Panicle contracted (!'- 2' long); one 

 of the staminate flowers barely pointed or short-awned near the tip, the other 

 long-awned from below the middle; lowest leaves very narrow. 1J. Alpine 

 mountain-tops, New England, New York, and northward. July. (Eu.) 



54. ANTHOXAtfTHUM,L. SWEET-SCENTED VERNAL-GRASS. 



Spikelets spiked-panicled, 3-flowered ; but the lateral flowers neutral, consist- 

 ing merely of one palea which is hairy on the outside and awned on the back : 

 the central (terminal) flower perfect, of 2 awnless chartaceous paleae, 2-androus. 

 Glumes very thin, acute, keeled ; the upper about as long as the flowers, twice 

 the length of the lower. Squamulae none. Grain ovate, adherent to the enclos- 

 ing paleae. (Name compounded of avBos, flower, and av6o>v, of flowers. L.) 



1. A. ODORATUM, L. Spikelets spreading (brownish or tinged with green) ; 

 one of the neutral flowers bearing a bent awn from near its base, the other short- 

 awned below the tip. 1J. Meadows, pastures, &c. ; very sweet-scented in dry

55. PHAL.ARIS, L. CANARY-GRASS. 



Spikelets crowded in a dense or spiked panicle, with 2 neutral mere rudiments 

 of a flower, one on each side, at the base of the perfect one, which is flattish, 

 awnless, of 2 shining paleae, shorter than the equal boat-shaped and often winged- 

 keeled glumes, finally coriaceous or cartilaginous, and closely enclosing the 

 flattened free and smooth grain. Stamens 3. Leaves broad, flat. (The an- 

 cient name, from <aXos, shining, alluding either to the paleae or the grain.) 



1. P. arundinacca, L. (REED CANARY-GRASS.) Panicle more & 

 less branched, clustered, a little spreading when old ; glumes winglesa, with flat- 

 tened pointed tips ; rudimentary flowers hairy, \ the length of the fertile one. ty
