This differs from Green Amaranth in the following ways: the inflorescence is stiff on Powell's Amaranth (floppy on Green Amaranth); it has stout midribs (thin on Green Amaranth); the styles are thick at the base (not thick at the base on Green Amaranth) and the number of tepals varies from 3 to 5 (always 3 tepals on Green Amaranth).

Bracts usually protruding beyond the styles. The longest bracteoles of the female flowers is about twice that of the perianth (= calyx plus corolla).

The styles are like micro-miniature TV yagi aerials.
