Mayweed, a plant of the composite family, with so much the aspect of the chamomile that some botanists place it in the same genus as anthemis cotula, while others regard the fact that the ray flowers are neutral as sufficient to characterize a separate genus, maruta. The plant is a native of Europe, and has become extensively naturalized in this country; and while it is very common along roadsides and in barnyards, it is not an aggressive weed upon cultivated grounds. It is also known as dog's fennel and stinking chamomile; it has not only the appearance of chamomile, but similar properties, but accompanied by a nauseous odor, which does not prevent its occasional use in domestic medicine. It is said that the fresh plant, especially if bruised, will cause blistering if applied to the skin. Its only importance is as an exceedingly common weed; and as it is an annual and easily exterminated, its presence is an index of careless cultivation.
