Glyceria pallida Trin. Pale Manna-grass. 
A slender semiaquatic, with stems 1 to 3 feet long. Found in very wet places along 
argins of ponds and slow streams, ranging southward from Canada to Ten- 
nessee. Rarely suffieiently abundant to form any considerable element in the 
native forage. 
Gymnopogon brevifolius Trin. Short-leafed Beard-grass. 
A slender, wiry grass, growing in dry, sandy soils along thiekets and in open pine 
woods from Delaware southward to Florida. It is a grass of no agricultural 
lue. 
Gymnopogon racemosus Beauv. Naked Beard-grass. 
Similar to the last, but of stouter growth and with broader leaves. Found in similar 
situations but more common, extending from New 
Jersey southward and westward to the Mississippi. 
Gymnothrix caudata. (See Pennisetum macrourum.) 
Gymnothrix latifolia. (See Pennisetum latifolium.) 
Gynerium argenteum Nees. Pampas-grass. 
- A stout perennial, 8 to 12 feet high, with mostly radi- 
cal, narrow leaves 3 to 6 feet long, and showy, sil- 
very white or rose-red panicles 15 to 30 inches long. 
A much-prized ornamental for lawn decoration. 
The handsome panicles are used for dry bouquets. 
Growing Pampas plu umes is an important industry 
the leaf sheath, then dried, and done up into e 
for shipment. Pampas-grass isa native of souther 
Brazil and Argentina, and there the long leaves are 
used for paper making, and a decoction of the 
rhizome is used as a diuretic. G. roseum is a horti- 
cultural variety, with pale, rose-colored plumes. 
G. variegatum is a form with variegated leaves. 
Hemarthria compressa. (See Rotibellia compressa.) 
Heteropogon contortus. (See Andropogon contortus.)

Hierochloé SR Wahl. Vanilla-grass; Seneca- 
(Fig. 48.) 
FIG. 3 ae ig grass; Holy- ; Sweet-grass. 
A rather alea sweet se ented perennial, 1 to 2 feet 
high, with short culm leaves and brownish panicles. Moist meadows and moun- 
tains of the Northeastern States, extending westward to Oregon. This grass, 
remarkable for its fragrance, has long, ereeping rhizomes, from which spring the 
flowering eulms and numerous long-leafed sterile or flowerless shoots. These 
long leaves are woven into small mats and boxes by the Indians, and find a ready 
market because of the sweet odor, which they retain for a long time. This odor 
resembles that of sweet vernal grass, but is more powerful, especially when dry. 
In some European countries it is believed to have a tendency to induce sleep, and 
bunches of it are hung over beds for this purpose. It makes a good turf, but is 
useless for forage.
