Molecular Phylogeny of Phacelia (Boraginaceae), within and between subgenera, sections and subsections.

Phacelia (Boraginaceae) contains two hundred species in North and South America, including three federally endangered species. California is the center of diversity with ninety-three species, of which thirty-nine are endemics. Traditional taxonomy based on morphology and chromosome number recognizes three subgenera, five sections and seven subsectional groups. This project addresses sectional phylogenetic patterns within Phacelia with the goal to fill sampling gaps across the genus to help answer genus wide phylogenetic questions. Work to date suggests that the species group Pulchellae is not monophyletic. Future work includes additional comprehensive sampling across each taxonomic group and molecular analyses with chloroplast and nuclear markers.
