Solanum pseudocapsicum
Solanum triflorum
Solanum pseudocapsicum is native from Mexico to Argentina, southern Brazil, and Uruguay. It is grown as an ornamental for its showy fruits, especially around Christmas. It occasionally escapes from cultivation in southern Florida and Texas. In Texas, it has become established and fairly common in Austin, in the Lower Rio Grande Valley, and in Goliad and Caldwell counties. Cultivated forms are usually glabrous, but some can have branched pubescence. The fruits are mildly poisonous when ingested by humans but can be highly toxic to dogs and some birds.
Solanum pseudocapsicum, along with S. diphyllum, has a distinctive leaf arrangement in which a longer, narrower leaf is paired with a shorter, often more rounded one.

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.
