Abstract

Integrating the information provided by different lines of evidence generated in previous studies, Phaseolus debouckii, a new species is described and illustrated. This species occurs only in central-southern Ecuador and north western Peru, mostly in what is known as the Amatope-Huancabamba Depression, and represents a sister species to Phaseolus vulgaris L. A comparison table with quantitative and qualitative morphological characters is given, as well as a distribution map and ecological information.
