Description
Solanum x rechei (rechei in honor of Argentinian botanist J.O. Reche) is a nothospecies (natural inter-species hybrid) from Argentina. The parent species were most likely S. microdontum and S. kurtzianum (Clausen 1998). It is a weedy species, common in a small area of Argentina where its parent species overlap in distribution. S. x rechei is notable for being a South American species that will tuberize under long days, a relatively rare trait among the South American wild potatoes.
Most populations of S. x rechei are diploid, but triploid populations also exist (Clausen 1998).
Jarvis (2008) predicts that this species will become extinct in the wild by 2055 due to climate change.

Cultivation
Clausen (1998) observed a low rate of pollen staining in this species, indicating reduced male fertility. I have found that berry production is poor even with hand pollination.
