There are 75 recognized species in the genus, some monoecious and some dioecious. The name amaranth was originally applied to the closely related genus Celosia. Amaranthus is cosmopolitan in tropical regions. Some species are cultivated as leaf vegetables, pseudocereals (with amaranth grain being collected), and ornamental plants.
