Under this general name are various local forms common in the Andean highlands and the Canary Islands, belonging to the species Solanum tuberosum subsp. andigena or Solanum chaucha. These are not bred varieties, but traditional forms preserved since the XVI–XVII centuries.
The characteristic features of the group are dark, almost black or brownish-purple skin and light yellow flesh. Tubers often have an irregular shape, deep eyes, and small size. In terms of maturity, the plants are usually classified as late or mid-late.
Potatoes of this group are distinguished by a mealy, starchy texture. Disease resistance varies significantly depending on the specific ecotype, which requires clarification when studying individual forms. The name is often descriptive due to the skin color.
