Solanum capsicoides, the cockroach berry, is a species of flowering plant in the family Solanaceae. It is native to eastern Brazil but naturalized in other tropical regions, where it sometimes becomes an invasive weed.[1]
This species had been included in S. aculeatissimum as variety denudatum by Dunal (Solanum denudatum of Bitter is S. humile as described by Lamarck). It was also included in the eggplant (S. melongena) under its junior synonym S. trongum (as var. sinuato-pinnatifidum), also by Dunal.[2]
In addition, the cockroach berry is sometimes referenced under the following obsolete names:
S. ciliatum of Blume from F.A.W. Miquel is an undetermined species of Lycianthes.
S. arenarium of Schur is S. villosum as described by Philip Miller.
S. arenarium of Otto Sendtner is a valid species
S. pentapetaloides of Bojer from Dunal in de Candolle is S. imamense.
