Cycloloma
''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,〔http://botany.csdl.tamu.edu/FLORA/kartesz/karchen4.htm〕 and tumble-weed.〔 page 16〕 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 half a meter 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.〔 page 455〕 The fruit is a utricle about 2 millimeters long containing a single seed. == Uses == 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. 〔Castetter, Edward F. 1935 Ethnobiological Studies in the American Southwest I. Uncultivated Native Plants Used as Sources of Food. University of New Mexico Bulletin 4(1):1-44 (p. 22)〕 The Zuni also grind the seeds, mix them with corn meal and make them into steamed cakes.〔Stevenson, Matilda Coxe 1915 Ethnobotany of the Zuni Indians. SI-BAE Annual Report #30 p.67〕 The Zuni also chew the blossoms and rub them all over the hands for protection.〔Stevenson, p.84〕
