Solanum aculeatissimum, Solanum viarum, Solanum aculeastrum
Solanum capsicoides, the cockroach berry, known as polohauai'i in Polynesia, is a flowering plant in the Solanaceae family. It is native to eastern Brazil but naturalized in other tropical regions, where it sometimes becomes an invasive weed.
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.
In addition, the cockroach berry is sometimes referenced under the following obsolete names:
S. arenarium of Schur is S. villosum as described by Philip Miller.S. arenarium of Otto Sendtner is a valid species
