✦ Synopsis

We conducted a joint Ecuador/Colombia/United States wild potato (Solanum sect . Petota) germplasm collecting expedition in Ecuador from April 13-July 1, 1991 . The goals of the expedition were to collect germplasm and study the species boundaries of all of the 25 Ecuadorian taxa accepted by current taxonomists . We made 126 collections of 24 of these 25 taxa, 113 as germplasm samples, 13 only as herbarium collections . We synonymize six of these 25 names (S . baezense Ochoa, S. cyanophyllum Correll, S . pichinchense Bitter & Sodiro, S. serratoris Ochoa, S. suffrutescens Correll as synonyms of S . andreanum Baker ; S . correllii Ochoa as a synonym of S. regularifolium Correll) . Four other names (S . chomatophilum f . angustifoliolum Correll, S . moscopanum Hawkes, S. solisii Hawkes, S. tundalomense Ochoa) could not be consistently distinguished from S. colombianum Dunal in the field. We are currently investigating them to determine their species status .
