I came across this plant in a disused orchard beside the Guadaiza River in Southern Spain. It is very prickly and the fruit looks like a tomato but is much harder and is a lemon yellow colour.
No interactions present.
... is a nomem ambiguum, and the current name for this species is Solanum linnaeanum.
Regardless of their taste, the fruits are (highly) toxic.

Caserio de las Maquinas is an old ruined building beside the Guadaiza River. It has an orchard that was obviously once very productive.
