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.

Description

A dryland species from eastern Bolivia.  Plants roughly six inches to a foot tall.  Stolons about a foot long.  Tubers small, less than an inch, round to ovoid.  Flowers white.  Berries round, about half an inch in diameter.

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

This species has both type A and B glandular trichomes which provide resistance to aphids by entrapment, similar to S. berthaultii (Lapointe 1986).
