Amaranthus hybridus A. A. Reznicek

Probably a native of tropical America and the southern United States, now a weed of dumps, farmyards and gardens, disturbed ground, and shores. The first Michigan collection is from Detroit (Wayne Co.) in 1866. Our specimens of this species all have the stem quite pubescent, especially around the inflorescence, although generally less so than in A. retroflexus. Some collections from shores of Lake Erie in Monroe Co. are apparently sterile hybrids with A. tuberculatus.
