A. A. Reznicek
A native of western North America, occurring usually in disturbed ground, dumps, sandy fields, and roadsides.
Collected as early as 1917 by O. A. Farwell in Oakland Co., though reported by him (Farwell, 1919, 1927) as A. hybridus. The 1867 report in Michigan Flora, Vol. 2 and the Field Manual of Michigan Flora (from Washtenaw, not Wayne Co.) has been re-determined as Amaranthus hybridus × A. powellii, though this still suggests the presence of A. powellii at that time. Despite these early reports, this plant has become common only in the last few decades.
The rigid spiny bracts of this species give it a superficial resemblance closer to A. retroflexus than A. hypochondriacus.
