Solanum gandarillasii (gandarillasii, in honor of Bolivian agronomist Humberto Gandarillas) is a Bolivian species, growing in dry environments.  Plants about six inches tall, occasionally up to a foot.  Stolons about a foot long.  Tubers very small, about half an inch. White flowers.  Berries small and round.

This species has been tentatively classified as vulnerable on the IUCN Red List (Cadima 2014).

Resistances

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

Cultivation

I have found this species difficult to germinate using the standard conditions for S. tuberosum.

Towill (1983) found that seeds of this species stored at 1 to 3 degrees C germinated at 70% after 19 years.
