* All the plants of this ad. order, digynia, are grasses, and comprehends much 
the greater part; though there are others of different characters arranged in their 
proper classes, as in MONANDRIA, cinna. —DIANDRIA, anthoxanthum .—HEX- 
ANDRIA, oryza, ehrharta, gahnia.—M ONCECIA, zea, tripsacum, coix, olyra, 
zizania, pharus. —DICECIA, restio —POLYGAMIA, cegilops, cenchrus,ischcemum, 
upkula, holcus, andropogon, manisuris, chrysitrix, spinifex. —Grass is defined to 
he a plant, having simple leaves, a stem generally jointed and tubular, a husky 
calyx, (called gluma) and the seed single. The leaves are food for cattle, the small 
seeds for birds, and the larger grain for man: none are poisonous. And it is observed, 
that nature hath so provided, that cattle (in grazing) seldom eat the flower intended 
to produce seed, unless compelled by hunger. 
f Anthistiria is easily distinguished from all the known genera of grasses by its 
four-valved calyx, for the division of the calyx is very essential in forming the 
character of grasses. 
J Panicum arlorescens , (tree panic grass) whose stem is scarce thicker than a 
goose quill, rises in India as high as the tallest trees. 
§ Striped riband grass, or reed grass, according to Linnaeus, is phalaris arun- 
denacra ; according to Aiton, it is arundo color ala.

perennial plant, vet several other vegetables secrete a sweet juice easily converted 
into sugar; as in America, a considerable quantity is obtained from the acer
