Comments: Formerly called Solanum siparunoides. This heavily spined climber is common on forest edges, in open pastures, and on roadsides, but occasionally also grows as a high-climbing liana in the forest, usually in old tree fall gaps. This wide-ranging plant is eaten by more ithomiine species than just about any other member of the Solanaceae in Costa Rica. It becomes increasingly scarce down the dry Pacific slope below Monteverde.
