(okadae in honor of Argentinian potato expert K.A. Okada) Primarily a western Bolivian species, ranging south into Argentina, growing in moist mid-elevation habitats.  Plants about a foot tall.  Stolons two feet long or more.  Tubers round to ovoid, reaching about an inch in diameter.  Flowers white.  Berries round and a little more than 1/2 inch in diameter.

Ochoa (1990) notes that this species is unusually vulnerable to late blight.  Vega (1995) found that this species is less frost tolerant than domesticated potato.

EBN of this species has not yet been determined.
