Solanum albornozii (albornozii, in honor of Ecuadorian potato expert Guillermo Albornoz) is a species from southern Ecuador.  Plants reach almost two feet tall.  Tubers are moniliform (like beads on a string).  White flowers.  Native habitat is slopes and forest borders around 7,500 feet (2300 m) (Correll 1962).

A study of nutrient content in wild potatoes found that this species was among the highest in a large number of minerals, including potassium, sulfur, zinc, manganese, iron, and copper (Jansky 2016).

Resistances

Vega (1995) found that this species is less frost tolerant than domesticated potato and Hijmans (2003) also found minimal frost tolerance.
