First flower of each glomerulus is staminate. Following flowers are pistillate. Each glomerulus has only one staminate flower. Typical to grain amaranth species. Flowers of upper glomeruli in the inflorescence are all staminate and the lower ones pistillate.
Basic unit is the same as the maniacs species.
Flowers are small and inconspicuous. When fertilization is prevented, pistillate flowers are successfully produced in the glomerulus. In all grain species, each flower is subtended by a sharp-pointed bract. No vernalization or low temperature requirements for flowering have been reported. Inflorescence length and branching is highly affected by day length.
