Abstract
The objective of this thesis is to clarify the taxonomy of Lupinus leucophyllus Dougl. The morphological variability observed, has historically rendered the group as difficult, although the species has clear diagnostic characters and is easily recognizable today. Morphological analysis is combined with thin-layer chromatography of alkaloids and geographic information to arrive at a feasable taxonomic treatment at the subspecific level. Principal Components Analysis of 34 morphological attributes resulted in clusters of similiar morphological affinity. Three subspecies are named based on the evidence: ssp. leucophyllus, ssp. retrorsus, and ssp. erectus. They are characterized by distinct morphological attributes, ecological adaptation, and geographic distribution. The subspecies leucophyllus contains three varieties. Varietal designations acknowledge morphologically distinct variants with broad distribution.
