GRAMINEJE. (GRASS FAMILY.) 
38. LOLIIH?!, L. Darnel. 
Spikelets many-flowered, solitary, and placed edgewise on the 
continuous rachis: the glume, except in the terminal spikelet, 
only one and external: — otherwise chiefly as in Triticum § Agro- 
pyron. (The ancient Latin name.) 
1. E. perenne, L. (Common Darnel. Ray or Rye-Grass.) 
Glume much shorter than the spikelet; flowers 6-9, usually aimless , 
sometimes awn-pointed. 1J. —Meadows, &c., naturalized. June.— 
A pretty good pasture-grass. 
2. E. tcmulentum, L. (Bearded Darnel.) Glume fully 
equalling the 5-7-flowered spikelet; awn longer than the flower (If 
long). (T) —Old fields, Massachusetts and Penn , scarcely naturaliz¬ 
ed. — Grain noxious, almost the only such instance in Grasses. 
30. EfciYUIUS, L. Lyme-Grass. Wild Rye. 
Spikelets 2 - 4 at each joint of the rachis, all fertile, each 2-7- 
flowered ; the uppermost flower imperfect. Glumes nearly side 
by side in front of the spikelets, rarely wanting. Paleae coria¬ 
ceous, the lower rounded on the back, usually awned at the apex, 
adherent to the involving paleae (whence the name of these Rye¬ 
like Grasses, *E \vpos, a hull , also an ancient name for some grain, 
from iXvto, to roll up). 
§ 1. Elymus proper.— Ghimes rigid , unequal-sided, netted. 
1. E. VirgfilliCUS, L. Spike rigidly upright , dense and thick 
(3' long), on a short peduncle usually included in the sheath ; spikelets 
2-3 together, 2 - 3-flowered, smooth, rather short-awned ; the rough 
and thickened strongly-nerved and bristle-pointed lanceolate glumes 
about their length. 1J. — River-banks, common southward. Aug.— 
Culm stout, 2°-3? high : leaves broadly linear, rough. 
2. E. Canadensis, L. Spike rather loose , curving (o'-9' 
long), on an exserted peduncle; spikelets mostly in pairs, of 3-5 
long-awned rough or rough-hairy flowers; the lance-awl-shupedglumes 
tipped with shorter awns. (E. Philadelpbicus, L./) Var. glaccif6- 
lius (E. glaucifolius, Muhl.) is pale or glaucous throughout, the flow¬ 
ers with spreading awns (1*' long). U — River-banks, in rich soil. 
3. E. strisitns, Willd. Spike dense but slender , upright or 
slightly nodding (3'-4' long); spikelets mostly in pairs, 1-2- (or 
rarely 3-) flowered, minutely bristly-bairy; glumes linear-awl-shaped 
or truly awl-shaped , bristle-awned , about thrice the length of the flowers, 
not counting their capillaty awn (which is 1' long) ; leaves rather 
narrow and sheaths smooth or hairy, or downy.— Var. villosus ( ... 
villosus, Muhl.!) has a somewhat stouter spike and very hairy glumes.
