Solanum lobbianum distribution Map note

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.  Tubers small and whitish.

Hawkes (1992) discussed the uncertain history of this species.  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.

Cultivation

I have found seeds of this species difficult to germinate.  They might require conditions different than the standard for S. tuberosum.  The seeds that I started with were old and had a low stated germination percent.

Accessions Evaluated

The following accessions were examined to prepare this profile.  I have evaluated 1/1 accessions currently available from the US potato genebank.

PI 567842

Unfortunately, I got no germination from this accession and it is no longer available.
