(Flea, Bane.) BoTANiCAi, Description.— 5f em erect, wand-like, five inches to Ave feet high, branching, hairy ajid furrowed. L&a/eea very narrow, witli rougli edges; lliose from the root cut-lobcd. I'lowers white, very nunieroaa, amall, of mean appearance, Irregularly racemoua upon the branchos, and constituting a large oblong panicle. The disk of the flowers yellow.

This is an. annual plant, common all over the world, seldom sonn in woods or on mountains, but grows in fields, commons, dry meadows and gladea in groat profusion, and is deemed by farmers one of the most troublesome weeds. It flowers in June to October. [This genus comprises eiglit species, three of which are considered to possess similar medicinal quali- ties, namely; E. canadense, E. philadclpUicum, E. annuum. It is quile probable that the plant as found in the shops, and most of the oil in liiar- ket, is prepared from the three, and perhaps other kinds, mixed indiscrimi- aaiely.

The E. canadense is the largest species, but lias fewer rays (forty

Medical History The plant has been, used since anterioi' to the settle- mem of tliia country. II is still called by its ahoriginal name of " CocosU." The Indians used it as a vulnerary, much as Arnica, Is used in homceo- pathic practice. It lias a host of common names.

Fleabane is the true Bnglish name. Colt's-tail, Mare's-tail, Daisj', Frost-weed, Field-weed, Skevish, etc., are names in common use with the country people, and apply to all the species of the plant. Tliese plants have a peculiar smell, most unfolded by rubbing them, and is not disagreeable. Their taste ia astringent, acrimonious, and bitter.

The two species having the strongest taste and odor are the E. phlladelphicum and E. annuum.

On analysis they are found to contain Tannin, Extractive, Gallic-acid, Amarin, and an Essential Oil. The oil is very pecnliar, as fluid as water, of a pale yellow color, a peculiar smell, somewhat like lemon, but stronger, and a very acrid taste. Medical authors do not agree as to which plant shall be decreed ofQcinal. Baflnesque mentions the E. phlladelphicum, and botanic writers follow him.

Wood and Stille name the E. canadense. Homceopathlsts settled upon the latter more by accident, perhaps, as that species was first mentioned.
