Description.—This very common roadside herb rises to a height of from 
6 to 20 inches, from a slender, creeping, perennial root, which, beside a multitude 
of filiform rootlets, gives off several long, reddish stolons. The s/em is simple or 
nearly so, erect, slightly grooved and roughly hairy. Leaves alternate; those 
from near the root wide-petioled, 2 to 6 inches long; those of the stem proper, 
shorter, sessile or nearly so, and all in their general outline more or less lanceo- 
late oblong, twice pinnately parted, the divisions linear, crowded and 3 to 5 cleft. 
Peduncles 3 or more; pedicels many, forming small, crowded, flat-topped corymbs 
at the summit of the plant. /Yeads many-flowered, radiate. nvolucre, of 2 to 3 
imbricated rows of ovoid-oblong scales, with a prominent midrib and brownish, 
scarious edges. ays 4 or 5, pistillate, with a short, obovate, reflexed limb, 
more or less 3-lobed. Disk-florets 8 to 12, bisexual. Ca/yx limb obsolete. 
Corolla tubular, the summit slightly inflated, 5-lobed, the lobes revolute, acute. 
Stamens 5, inserted upon the tube, and rising slightly above the face of the 
corolla. Anthers adnate, without tails at the base. Szy/e long, upright, slender, 
rising above the anthers. Stigma 2-cleft, the divisions recurved and fringed at 
their tips. Receptacle small, usually flat and chaffy. Achenia oblong, flattened

—Yarrow is an abundant weed in old, dry pastures, 
along roadsides and in fields in the northern parts of America, extending in this 
country, as well as in Western Asia and Europe, high in the colder latitudes. It 
came to us from Europe, being now fully naturalized. The white or sometimes 
pink flower-heads blossom all summer, Among the Pah-Ute Indians, according 
to Dr. Edward Palmer, this plant is much used in decoction for weak and dis- 
ordered stomachs. Linnzus says, that for a time the Swedes used Yarrow in 
lieu of hops in the manufacture of beer, and claimed the beer thus brewed to be 
a greater intoxicant. Millefolium has been dismissed from the U.S. Ph. In the 
Eclectic practice it is used in an infusion, tincture, or the essential oil. 
virtues of this genus are said to have been discovered by Ach 
History and Habitat.
