Cycloloma is a monotypic genus which contains the sole species Cycloloma atriplicifolium, which is known by the common names winged pigweed, tumble ringwing, plains tumbleweed,[1] and tumble-weed.[2] This plant is native to central North America, but it is spreading and has been occasionally reported in far-flung areas from California to Maine to the Canadian prairie. It is considered an introduced species outside of central North America. This is a bushy annual herb forming a rounded pale green clump which may exceed 0.5 m (1 ft 8 in) in height. It is very intricately branched, with toothed leaves occurring near the base. The spreading stems bear widely spaced flowers are small immature fruits fringed with a nearly transparent membranous wing. In autumn, the plant forms a tumbleweed.[3] The fruit is a utricle about 2 millimeters long containing a single seed.

The seeds are eaten as a food staple by Native American peoples including the Zuni and Hopi. The Zuni people mix the seeds with ground corn to make a mush.[4] The Zuni also grind the seeds, mix them with corn meal and make them into steamed cakes.[5] The Zuni also chew the blossoms and rub them all over the hands for protection.[6]
