Description

Solanum x rechei 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.
