Pigweed, Rough
 

Amaranthus retroflexus
A 2-4' plant with a rough, hairy, often reddish stem. The long-stalked, alternate leaves are oval to lance-shaped. The chaffy greenish flowers are in stout, cylindrical terminal and leaf axil spikes and are intermingled with bristle-like bracts longer than the flowers. Blooms August-October in waste areas, cornfields, roadsides.

The flower spikes are wider and less spreading than those of Slender pigweed (A. hybridus).
