 green, or often glaucous ; spike rather loose and spreading, 4, to 8' long, generally 

 nodding, raohis hairy, spikelets more or less hairy, in 23 and Ss, 3 to 6-flo*ered, 

 awns of the fis. usually curved, longer (7 to 11") than those of the glumes. — A 

 tall grass, looking like Eye, with long, recurved, waving spikes. River banks. Aug.

 1 to 3-floweired ; mims 3ior i times as long as the pale. — ij. Mass. to Penn., W. to 

 Ohio, rare. A small and slender species. July. (B. villosus MuhL is some larger, 

 with very hairy glumes.)

 compressed, glabrous as well as the striate sheaths ; spike thick, erect, 6 to 8" ; 

 spikelets in pairs, about 7 -flowered, awnless, all clothed with a soft pubescence; 

 glumes shorter than the fls. — Lake shores, Min. and Can. W.

 generally glaucous and with the steaths striate ; spike 4 — 6' long, erect ; rachis 

 nearly smooth, flexuous; spikelets remote, diverging, almost horizontal, 2 — 3- 

 flowered ; glumes 0, rarely 1 or 2 ; fls. smoothish ; lower palese terminating in a 

 very long awn. — y An odd-looking grass, in moist woods, N. States, common. Jl. 



50. LO^LIUM, L. Daenel Grass. Spikelets many-flowered, sessile, 

 remote, with the edge to the rachis ; glume to the lower spikelet single, 

 to the terminal one 2 ; palese herbaceous, subequal, lower one short- 

 awned or mucronate, upper bifid-toothed. 



1 Ii. perSnne L. Eat Daenel. Smooth ; culm terete, 1 — 2f ; Ivs. lance-linear, 

 shining-green, on striate sheaths with truncate stipules ; raohis flexuous, grooved, 

 5 — 6' long ; spikelets awnless, about 16, longer than the glume, 7 — 9-flowered, 

 alternate, in two opposite rows ; lower paleae 5-veined, upper with 2, prominent, 

 rough keels. — U Meadows, cultivated grounds, etc. May, June. § Eur. 



.2 L. temul^ntum L. Poisonous Daukel. Culm terete, smooth, 2f; Ivs. lance- 

 linear, rough-edged, and with the sheaths, smooth on the surface ; stip. truncate ; 

 rachis flexuous, 4 — 6' long ; spikelets much compressed, 5 — 7 -flowered, Tiot longer 

 than the glume ; lower pale 5-veined, produced into an awn twice its length. — (D 

 Remarkably distinguished from all other grasses by its poisonous seeds. N. Eng. 

 to Penn. July. § Eur. 



51. TRIT'ICUM, L. Wheat. (Lat. tritum, rubbed or ground ; al- 

 luding to the manner of its preparation for food.) Spikelets imbricated 

 in 2 rows, sessile on the teeth of the rachis, about S-flowered, with the 

 upper flowers abortive ; glumes 2, equal, opposite, ovate, concave, mu- 

 cronate ; paletB 2, lower awned or mucronate ; scales 2, collateral. — ^Fls. 

 arranged in spikes.

 nodes somewhat inflated, 3 to 6f ; lv.s. lance-linear, veined, roughish above ; stip. 

 tnmcate ; -spike parallel, somewhat 4-sided ; spikelets crowded, broad-ovate, 

 about 4-flowered ; glumes ventricous ; awns of Iho upper paleffi generally longer 

 than the flowers.— (J) and ® This is without doubt the most valuable plant of tho 

 Order. Cultivated from the earliest historic times. Many varieties are known to 

 farmers, classed as Summeb "Wheat, and Winteb Wheat ; Awned or Awnless.
