Solanum tarnii (tarnii, in honor of T.R. Tarn, who was involved in the first collection of this species) is native to Mexico, primarily Hidalgo.  Plants roughly 2 to 3 feet tall.  White flowers.  Very little has been written about this species.

Jarvis (2008) predicts that this species will become extinct in the wild by 2055 due to climate change.

Resistances

Vega (1995) found that this species is more frost tolerant than domesticated potato.

Crosses with other species

Jackson (1999) found that 7-13% of varieties of this species produced 2n pollen, which would be effectively tetraploid and 2EBN.
