Solanum triflorum
Solanum bahamense
Solanum triflorum is found in South America (Argentina) and is also considered to be native to central and western North America. It is occasionally adventive in the eastern United States. It is poisonous to livestock and can become a serious weed in cultivated fields, especially in the Great Plains.

Solanum bahamense is morphologically variable, especially in leaf shape, hair morphology, prickle density, and corolla color. Using morphological and molecular data, R. Strickland-Constable et al. (2010) established that several formerly recognized taxa are encompassed within its range of variability and should be considered as synonyms of S. bahamense. It is unique among the North American spiny solanums in having stellate hairs on the inner (adaxial) surface of the anthers. Solanum bahamense occurs in southern Florida and the Keys and throughout the Caribbean.
