det. M. Nee, 2002
NEW York, Tompkins Co., Varna Experimental plots for
vegetable crops of Cornell University, 2 miles E of Ithaca.
The Cucurbitaceae and Lycopersicon plots with Portulaca
oleracea, Chenopodium album, Ambrosia artemisiifolia,
Mollugo verticillata, Amaranthus albus, A. hybridus, A.
retroflexus.
Herb, much less common than A. hybridus (no. 52290) in
these plots, but both species here and almost all
distinguishable, most easily by the fresher green color of A.
hybridus along with the more visible and pronounced red
tinge and stripes on the stems. Amaranthus retroflexus has
shorter and more congested inflorescence branches in the
terminal portion of the plant. The terminal inflorescence
portions of the lower, spreading side branches are less robust
than on the terminal one in both species. Specimens of this
number from two nearly identical plants.
