This page is a draft, part of our ongoing wild potato project. I’ll probably be adding information to the species pages through 2020 at least, but I’m making them public since they may be useful even incomplete.

Solanum gandarillasii (gandarillasii, in honor of Bolivian botanist Antonio Gandarillasii) 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.

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