Plants in the Amaranth Family (Amaranthaceae) are annual or perennial herbs (rarely subshrubs) with simple, exstipulate (lacking stipules) leaves, small or minute flowers with a superior ovary, and small, mostly dry, bladder-like, single-seeded, indehiscent fruit. Some plants in the Amaranth Family are major agricultural weeds, while others are cultivated for use as cereal grains or potherbs.
