Description
Solanum albornozii 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).
The specific epithet, albornozii, honors Argentinian botanist Antonio Albornoz. While there is no completely standardized pronunciation for scientific names, the most common way to pronounce this species is probably so-LAY-num al-bor-NOZ-ee-eye.
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.
