Genome-level phylogenetics in the taxonomically complex Camassia and Hastingsia (Asparagaceae).

Species delimitation has been an open question in Camassia and Hastingsia (Asparagaceae), two genera of ecological importance in a range of habitats in North America. Camassia comprises six recognized species, including the western C. quamash (with eight subspecies) and the disjunct eastern C. scilloides. These two widespread taxa occur sympatrically with one or more of the other four less-common species. The number of species recognized in Hastingsia has ranged from two to four. These genera provide a case study for better understanding speciation and for the application of integrative taxonomy. One approach we are applying is the inference of evolutionary patterns using restriction site-associated DNA sequencing (RADseq) data. We have recovered thousands of loci across approximately 280 individuals. Results confirm the utility of these data for phylogeny inference at this level, resolving relatively deep nodes along with many infraspecific relationships.
