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 lobbianum

Common Name(s):







Cytoplasm Type:


Solanum lobbianum (lobbianum, in honor of William Lobb, a British plant collector who first collected the species) is a species of very small distribution in Ecuador and possibly Colombia.

Hawkes (1992) discussed the very interesting history of this species and the mystery of its origin.  It was first collected in 1843 and the species was described from that collection by Bitter in 1913.  It was thought to have been collected in Colombia, but it was not found there in subsequent expeditions over the next nearly 150 years.  In 1991, Spooner, Castillo, and Lopez rediscovered the species in Ecuador.  The most likely explanation is that the original collection was made in Ecuador.

I have found seeds of this species difficult to germinate.  They might require conditions different than the standard for S. tuberosum.
