PaniCUM crus-galli. Cock-foot Panicam, barnyard grass, (a.) Thie coarse homely grass is said to be an inhabitant of all quarters of the globe. It is usually found in the latter part of summer, rather abundant along drains of barnyards and other waste places.
&lama glauca. Bristly Fox-tail grace, (a.) All our weed-like epeciea of this are believed to be natu ralized strangers here. This one weeny makes its appear ance in abundance among the stubble, after a wheat crop, and is frequent in pastures, orchards, etc., when not kept down by a more valuable growth. The S. viridis, called green fox-tail or bottle grave, is about equally worthless, but not quite so prevalent.
Set aria virtieellata, (a.) The adhesive brietlea of this epeciea, frequenting gardens and neglected lots, are cal culated to make it something of a nuisance if permitted to become abundant.
Cenchrus tribuloides. Bar grass, hedge-hog grass, (a.) This yeatilential nuisance is quite abundant in the sandy diatncts of New Jersey and along the great northern lakes.
Cynodon daetylon. Dog's-tooth grass, Bermuda grass, (p.) Of this grass, which has found its way from Europe into Virginia and other southern States, Mr. Elliott remarks; The cultivation of it on the poor and extensive sand-hilla of our middle country, (viz., in South Carolina,) would probably convert them into sheep-walks of great value; bat it grows in every soil, and no grasa in close, rich land, is more formidable to the cultivator. It must,
therefore, be introduced with caution.
Bromus secalinus. Cheat, chess, broom grass, (a,) This is a well known intruder among our crops of wheat and rye; and often appears in the same fields for a year or two after the crops, but is soon choked out by the peren nial grasses. This plant ie an annual, and easy to over come by care in sowing clean wheat, by keeping fence corners and field -borders clear and in establishing a proper rotation in cropping. The vulgar error that this grass is merely transmuted wheat, came to us with the earliest immigrants, and, notwithstanding the boasted march of mind, it yet prevails among a certain elate of farmers to a considerable extent.
Tritieuin repens. Couch grave, Qoitch grass, (p.) This species of triticum, which is quite distinct in habit from cultivates wheat, has found its way into some dis tricts of our country, and is a pernicious intruder, when fully introduced, by reason of the exceeding tenacity of life in its rhizomae, or creeping subterranean stems.
Andropogon nutans. Woo3 grass, Indian grass, (p.) This and two or three other species of native Indian grasses are common in our sterile grounds, and are no better than mere weeds.
