hard for a meadow grass : of many varieties, introduced from Europe ; spikelets 

 4- S-flowered ; lower palct cither pointless or short-awned. 2/ 



T. VUlgare, WHEAT. Spike dense, somewhat 4-idr.l ; tin- spikrl, -H 

 crowded, 4- 5-flowcred, turgid; glumes veutricosc, blunt; palrt either a 

 or awnless ; grain free. 



T. Spelta, SPELT. A grain rarely cult, in this country; spike flat, the 

 rhachis fragile, breaking up at the joints ; grain enclosed in tlic paler-, i 



Secale cereale, UVE. Tall ; spike as in wheat; spikelcts with onlv >. per- 

 fect flowers ; glumes a little distant, bristly towards the ba,-e ; low.-r pa'let veu-

+-*-*- Glumes 6 at each joint, in front of the 3 spikelets, forminej on inrolucre. 



Hordeum VUlgare, COMMON BARLKY, from the Old World : spike 

 dense, the 3 spikelets at each joint of the rhachis all with a fertile flower, ita 

 lower palet long-awned. 



H. distichum, T\VO-ROWED BARLEY, from Tartary : only one spikelet 

 at each joint of the rhachis with a fertile flower, the two lateral spikelets being 

 reduced to sterile rudiments, the flowers therefore two-rowed in the spike. i 



i- -t- -t- -t- Spikelets in a contracted panicle or seeming spike, or if spiked some- 

 wltat on one side of the rhachis : each with a single p< /// flower, //.< /<"/>/.s 

 of coriaceous or cartilaginous tcxtnr,- : by the side of it are either one or two 

 thin palets of a sterile usually neutral flower. 



Setaria, FOXTAIL-GRASS. Spikelets in clusters on the branches of tho 

 contracted spike-like panicle or seeming spike, these continued beyond them 

 into awn-like rough bristles ; but no awns from the spikelets themselves. 

 Weeds, or the last one cult. ; all from Old World ; fl. late summer. 



S. glauca, COMMON* FOXTAIL : in all stubble and cultivated grounds ; low ; 

 spike tawny yellow, dense ; long bristles 6-11 in a cluster, rough upwards (as 

 also all the following) ; palets of perfect flower wrinkled cros.-wi-r. 



S. viridis, GREEN FOXTAIL or BOTTLE-GRASS; has less dense and green 

 spike, fewer bristles, and palets of perfect flower striate lengthwise. 



S. Italica, or GERMA.NICA, ITALIAN MILLET, BENGAL GRASS, &c. Cult, 

 for fodder, 3 - 5 high, with rather large leaves, a compound or interrupted so- 

 called spike, which is evidently a contracted panicle, sometimes G' - 9' long and 

 nodding when ripe; bristles short and few in a cluster; palets of the fertile 

 flower smooth. 



Panicum (Digitaria) sanguinale, FINGER-GRASS or CRAB-GK\*S. 



Chiefly a weed in cult, fields in late summer and autumn, but useful in thin 

 grounds S. for hay; herbage reddish; spikes 4-15, slender, digitate, nearly 

 1-sided ; spikelets seemingly 1-flowered with 3 glumes ; no awns. 



P. Crus-galli, COCK'S-FOOT P., or BARXYARD-GRASS. Common weedy 

 grass, of moist barnyards and low rich grounds : coarse, with rather broad Iruvr-, 

 and numerous seeming spikes along the naked summit of the floweriuir -tnn-, 

 often forming a sort of panicle ; spikelets containing one fertile and our >terilc 

 flower, the lower palet of the latter bearing a coarse rough awn. i 



P capillare, WITCH GRASS of stubble and corn-fields in autumn. Inning 

 a very open capillary panicle, would be sought under another division ; it is a 

 mere weed. 



B. Stems not hollow, pitfii/. 



1. Spikelets clustered or smtti n>l in mi ample panicle, each icith one perfect and 



one neutral or staminate flower. 

 * Witltoiit silhi-ilown : </lttmes, frc. russet-broum, cri,i<-< />. 



Sorghum. VUlgare, INDIAN MILLET, PUKKA, or DOCRA. &C., from Africa 

 or India; the var. CERNUUM. GTINLA CORN, has dcnsch contracted panicle, 

 and is cult, for the grain. Var. SACCIIARATUM, SWEET SORGHUM, CmNESB 

 SUGAR-CANE, IMPIIEE, &c., cult, for the syrup of the stem ; and BKOO.M-CORN. 

 for the well-known corn-brooms.
