LIST OF SEEDS, BULBS, TUBERS, ETC. I1g 
awn borne much below the middle of the glume, some- 
what surpassing it; grain glabrous. Deyeuxia confinis 
(Kunth}. Swamps, Northern and Western New York 
(especially Penn Yan, Startwell) and Pennsylvania, 
Minnesota and westward. July. 
LEERSIA, Swartz.—White Grass. 
L. Oryzoides—Rice cut-grass:—Panicle diffusely 
branched; spikelets flat, rather spreading (24—3” 
long), stamens three; glumes strongly bristly-ciliate 
(whitish). Very wet places; Massachusetts to Minne- 
sota and southward; common. August. 
Elymus, L.:—Wild Rye:—Spikelets two to four at 
each joint of the rhachis of a terminal spike, all fertile 
and alike, sessile, each one to seven flowered. Glumes 
conspicuous, nearly side by side in front of the spikelets, 
two for each spikelet, forming an involucre to the 
cluster. Flower coriaceous; the glume rounded on the 
back, acute or awned at the apex. Grain adherent to 
the involving glume, whence the name, an ancient one 
for some grains (froni «Ave, to roll up). 
SPIKE LARGE AND STOUT. 
E. Virginicus, L.:—Culm stout, 2—3° high; spike 
rigidly upright, dense (2—3' long, 6” thick), the short 
peduncle usually included in the sheath; spikelets two 
to three together, two to three flowered, smooth 
rather short-awned, about the length of the thickened 
strongly-nerved and bristle-pointed lanceolate glumes. 
River banks; common. August. 
E. Canadensis, L.:—Spike soon nodding (5—0’ 
long), on an exserted peduncle; spikelets mostly 
in pairs, of three to five long-awned rough or 
rough-hairy flowers; the awl-shaped glumes tipped
