Solanum pseudocapsicum
Solanum chenopodioides
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 chenopodioides has been introduced sporadically and is occasionally adventive in North America. It is distinctive in having the fruiting peduncles strongly reflexed downward, but is otherwise difficult to distinguish from S. pseudogracile, with which it may be conspecific.
The illegitimate superfluous name Solanum gracile Dunal has often been used for S. chenopodioides (for example, J. K. Small 1913; A. E. Radford et al. 1968). W. G. D’Arcy (1974) included S. gracile (and its replacement name S. ottonis) in the synonymy of S. nigrescens but the taxa are distinct.
