in shape, about long and wide, borne on long peduncles. There is near certainty that ''A. hypochondriacus'' is the common ancestor to the cultivated species ''Amaranthus'' used as a grain or pseudocereal, however the later series of domestication to follow remains unclear. There has been opposing hypotheses of a single as opposed to multiple domestication events of the three grain species. There is evidence of phylogenetic and geographical support for clear groupings that indicate separate domestication events in South America and Central America. '' A. hybridus'' may derive from South America, whereas '' A. caudatus'', ''A. hypochondriacus'', and '' A. quentiensis'' are native to Central and North America.
