Phylogenetic Relationships Among the Iris hartwegii Complex Based on cpDNA, nDNA sequences, biogeography and morphometrics. Erin Riggs1 and Carol A. Wilson2.

Iris is a large and morphologically diverse genus with 280 species distributed in the Northern Hemisphere. In the Sierras and southern California transverse ranges the Iris hartwegii complex; as currently circumscribed is comprised of four subspecies: I. h. ssp. columbiana, I. h. ssp. hartwegii, I. h. ssp. australis, and I. h. ssp. pinetorum. Previous phylogenetic and phenetic research included morphology and RAPDs (Riggs, 2002), and sequence data from the ribosomal internal transcribed (ITS) region (Wilson, 2009 ), provided some information on this species complex but have not fully clarified relationships. This proposed research will use the combined techniques of phylogeography and phylogenetics to investigate the I. hartwegii complex and reveal phylogenetic events as well as the present day and historical distributional patterns across the landscape.
