Solanum pseudocapsicum
Solanum triquetrum
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 triquetrum is widespread in central, southern, and western Texas. It could be confused with S. dulcamara, which also has shiny green dots at the corolla lobe bases, but the flowers of S. triquetrum are white and the leaves more sharply triangular. Leaf shape and size in S. triquetrum are extremely variable (S. Knapp 2013).
