Echeveria tobarensis Berger, 1930:476
Taxonomy & Nomenclature
Synonym/s: Urbinia lurida Rose, 1911:301 (basionym)
Last record: 1908
Rediscovered in December 2010
This species was known only from four plants collected by Edward Palmer (1829-1911) in 1908. Many botanists had tried to relocate this species but were unsuccessful until Julia Etter and Martin Kristen found it again in December 2010. It goes to show just how many species are probably still out there to be discovered, since if Palmer had not found those four plants nobody would have even known the species existed, and hence would not have tried to find it (again).
