GAMOPETAL01113 E2COGENS—PETALS MORE OR LESS UNITED, Sambucus Canadensis. Common Elderbueb, (e.) This indigenous shrub is very tenacious of life, and inclined to spread extensively along fence-rows and hedges, giving the premises a very slovenly appearance.
Dipacscua sulcestris. Mill Tenon!, wild teasel, (b.) TMe coarse European weed is completely naturalized in some localities, and is not only worthless, but threatens to become a nuisance if not attended to.
Vernonia noveboracensis. Wild Irma Weed, (p.) A coarse native plant, quite common in moist, low grounds, and slung fence-rows. The rout of this must he cut like the Canada thistle before the flowering season in spring, or the danger will be imminent of its over-running the whole area in a short period by means of its floating seeds Enpatorium purpureum. Trumpet Weed, joe-pye weed, (p.) Several varieties of this tall, stout weed are indigenous on our moist low grounds.
Ater eritoldes. Heath-like Aster, (p.) Numerous species of this large American genus meet the eye of the farmer, in the latter part of summer, in his woodlands, low grounds, borders of thickets, etc., some of which are quite ornamental, but the little bushy one here mentioned is about the only one which invades our pastures to any material exteut. in neglected old fields, it often becomes as abundant as it is always a worthless weed.
Zigeron canadenss. Horse Weed, butter weed, (a.) This American weed has diffused itself all over our coun try, and his said, has reached and pervaded all Europe. The cultivation of hoed crops will clear the fields of this pest. Other varieties of the same genus infest meadows; which, if the evil becomes too burdensome, must be plowed up.
Erigeron strigosum. Flea-bane Daisy, (a.) This very common native weed is apt to be abundant in the first crop of upland meadow after the usual routine grain crop. After that, especially in good lands, it becomes more rare, being probably choked out, like many other weeds, by the valuable grasses.
Solidago nemoralis. Golden Rod, (p.) Several species of golden rod occur along fence rows, borders of woods' and thickets, and intrude upon neglected pasture fields.
Ambrosia trifIda. Great Rag Weed, (a.) A coarse, ugly native weed, common in waste places.
Ambrosia artemisicefala. Bitter Weed, rag weed, (a.) This indigenous, bushy weed, occurs in most cultivated grounde, and is most abundant among the stubble, after a crop of wheat. But if th .1 land be good, the plant seems to be smothered or choked out the next season by the usual succeeding crop of clover and the grasses. It is always ready, however, to make its appearance whenever the grassy turf is broken up by the plow.
Eanatum strumartum. Clot-weed, cockle-bur, (a.) This vile weed, of obscure origin, bus the appearance of a naturalized stranger in our country, and seems, fortun ately, not much inclined to spread. The burs are a great annoyance in the fleeces of sheep.
Xanthium spinosum. Thorny Clot-bur, (a.) This execrable foreign weed is fast becoming naturalized in many portions of our country, particularly in the southern States. It may be frequently seen also along the side walks and waste places in the suburbs of our northern seaports. It is stated that the authorities of a southern city a few years since enacted an ordinance against the offensive weed, in which enactment it was denounced by the misnomer of Canada thistle. This plant may be destroyed with the hoe in the latter part of summer—iu September.
Bidens frondosa. Bur Marigold, (a,) Worthless native weeds in gardens, corn fields, etc., and particularly disa greeable by reason of the barbed awns of the fruit, which adhere in great numbers to clothing.
Bidens bipinnatus. Spanish Needle, (a.) This, like the preceding, if not carefully watched and extirpated, is a great pest in cultivated lots. Another species, B. Ch y santhemoides, known as Beggar-ticks, is rather showy, with its head of yellow-rayed florets, and is frequently found along rivulets and vulets in autumn. They are all regarded as nuisances on account of their adhesive fruit. Maruta cotula. May-weed, foetid chamomile, (a.) A disagreeable little foreign weed, which is extensively naturalized, and in bad odor among us.
