This page is a draft, part of our ongoing wild potato project. I’ll probably be adding information to the species pages through 2020 at least, but I’m making them public since they may be useful even incomplete.

Solanum stipuloideum

Common Name(s): Monte ch’ogue, Monte phureja

Synonyms: S. capsicibaccatum, S. circaefolium, S. soestii

Series: Circaefolia

EBN: 1

Ploidy: Diploid

Segregation: Disomic

Self-compatible: No

Cytoplasm Type: W (Hosaka 2014)

Description

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).

This species can survive frosts down to 26 degrees F (-3.5 C) (Li 1977, as S. capsibaccatum).

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.
