glume, but there is no articulation of the pedicel, and it seems better 
to unite it with a few other exotic genera in a tribe or sub-tribe of 
Poacec. 
1. Milium effusum, Linn. (fig. 1159). Spreading M.—A tall, slender 
Grass, often 4 or 5 feet high, with rather short, flat leaves, and a long, 
loose, slender, and spreading panicle of small, pale green or purple 
spikelets. Empty glumes concave but not keeled, 1 to 1§ lines long, 
nearly smooth. Flowering glume almost as long, very smooth and 
shining. Palea nearly similar but rather smaller, faintly,2-nerved, and 
notched at the top. 
In moist woods, widely spread over Europe, Asia, and North America, 
extending from the Mediterranean to the Arctic Circle. Common in 
Britain. Fl. swmmer. 
III. PANICUM. PANICUM. 
Spikelets either in a loose or close and spike-like panicle, or along one 
side of the simple branches of a panicle, usually small, 1-flowered, rarely 
awned. Outer glumes usually 3; the first or lowest small, sometimes 
very minute, the next always empty, the third empty or with an im- 
perfect or male flower in its axil. Flowering glume concave, of a 
firmer texture, hard when in fruit. Palea like the flowering glume, but 
rather smaller, and more or less 2-nerved. 
A vast genus, chiefly tropical or North American, with a very few 
Species spreading into Russian Asia and Europe, including most of 
the cultivated Millets of southern Hurope, Africa, and Asia. It is in 
most cases easily recognised by the small outer glumes, although 
in some species reduced to an almost microscopical scale. Many 
botanists remove the following species into three separate genera distinct 
from the true tropical Panicums. 
Spikelets 2 together, along one side of the linear, digitate 
branches of the panicle. (DIGITARIA.) 
Spike-like branches of the panicle 2 to 4 inches long. : . LP. sanguinale. 
Spike-like branches not above an inch long - . 2. P. glabrum. 
Spikelets crowded in a simple or branched, spike- like panicle. 
Spike-like panicle cylindrical, the spikelets intermixed with 
numerous, long, awn-like bristles. (SETARIA.) 
Bristles rough with reversed hairs, felt as the spike is drawn 
dowitwards through the hand. . 3. P. verticillatum. 
Bristles rough with erect hairs, felt as the spike. is pushed 
upwards through the hand. 
Flowering glume marked with transverse wrinkles. . 4. P. glaucum. 
Flowering glume not wrinkled 5. P. viride. 
Panicle pyramidal, without awn-like bristles, but the spikelets 
sometimes coarsely awned (HECHINOCHLOA) . ‘ ‘ . 6 P. Crus-galli. 
1. P. sanguinale, Linn. (fig. 1160). Fingered P.—An annual, with 
stems from 1 to 2 feet long, more or less spreading or creeping at the 
base, then ascending or erect. Leaves flat, more or less hairy. The 
panicle consists of 2 to 6, or rarely more, simple, slender branches, 
2 to 4 inches long, and all spreading from nearly the same point at the 
top of the peduncle, so as to appear digitate. Spikelets in pairs along 
one side of these branches, one sessile, the other shortly stalked, each 
about 1 line long. First glume very minute, almost microscopic ; the 
second concave, and about half the length of the third, which is nearly
