Phylogenetics in three groups of perennial Lupinus in California.

The perennial lupines of California present taxonomic and phylogenetic challenges, as the species within the group are not well defined and the group itself is of fairly recent derivation. Currently, while it is understood that the perennial lupines are probably monophyletic, the phylogeny within the group has not been clearly elucidated. Reticulate evolution and low sequence divergence compound the problems faced in analyzing the phylogeny of this group. My research indicates significant conflict between cpDNA and nuclear DNA for samplings within three groups of Lupinus: Albicaules (sensu Isley 1998), L. albifrons (as described by Isley 1998), and Arborea (sensu Agardh 1835). I will present my findings to date based on sequence analysis of cpDNA non-coding regions and the low-copy nuclear region LEGCYC-A (Citerne 2005) from specimens within these groups.
