Chenopodium ambrosioides of Michigan Flora.

Railroads, alleys, and disturbed ground. A native of tropical America, collected by the First Survey in Calhoun and Kalamazoo Cos. in 1838, but recently only rarely collected. The strong aroma of this plant may persist for at least 50 years in dry specimens. The larger leaves may be essentially entire or coarsely toothed, but the smaller ones (if any) of the axillary inflorescences are essentially entire.
