Croton eutrigynus A. Gray

Plants densely velvety appressed-tomentose. Leaf blades suborbiculate, length mostly less than 2 times width, apex rounded to broadly acute. Pedicels, at least some, recurved in fruit.

Flowering May–Nov. Floodplains, old pastures, loamy soils, roadsides; 50–600 m; Ariz., Ark., Ill., Ind., Kans., La., Mo., N.Mex., N.C., Okla., S.C., Tex.; Mexico (Coahuila, Nuevo León, Tamaulipas).

Variety lindheimerianus is somewhat weedy and is adventive to central North Carolina, where it has persisted at the same site for over 50 years; it presumably is introduced also in South Carolina.
