Solanum stipuloideum is a wild potato species native to northwest and central Bolivia.  Primarily a woodland species, growing in moist soils (Ochoa 2004).  Leaves nearly simple, with just a few small, interjected leaflets.  Plants about 12 to 18 inches tall.  White flowers.  Berries long and pointed.

S. stipuloideum and its close relative S. neocardenasii appear to be the closest South American relatives to the North American wild potato species (Spooner 2018).

Resistances

This species can survive frosts down to 26 degrees F (-3.5 C) (Li 1977, as S. capsibaccatum).  Vega (1995) found that this species (as S. circaefolium) is about as frost tolerant as domesticated potato.

Pelletier (1999) observed that this species does not bear glandular trichomes as S. berthaultii does, but deters Colorado potato beetle similarly, and suggested that it probably produces semiochemicals that are responsible for the deterrence.

Crosses with other species

Watanabe (1991) found that 5.6% of varieties of this species (as S. circaefolium) produced 2n pollen and Jackson (1999) found 4-7%, which would be effectively tetraploid and 2EBN.
