Euphorbia nutans is a species of euphorb known by the common names eyebane and nodding spurge. It is native to the eastern United States and parts of South America. It is known as a weed in parts of its native range, as well as in areas where it has been introduced.[1] This is an annual herb growing erect with pairs of oblong leaves along its stems. The leaf may be up to 3.5 centimeters long, hairy or hairless, and finely toothed. The inflorescence may be solitary or borne in clusters. Each inflorescence is a cyathium, with flat white or red appendages surrounding the actual flowers. At the center of the array of appendages are several staminate flowers surrounding one pistillate flower. The latter develops into a fruit, which is a capsule about 2 millimeters wide.
