Phylogenetics within <i>Camassia</i> (Asparagaceae): examining difficult taxonomy and unusual variation using genomic restriction-site-associated DNA sequencing data.

ABSTRACT:

Premise

Diversification of Camassia (Asparagaceae) in North America has shaped variety in morphological, ecological, and reproductive traits, and resulted in a classification with ambiguity in taxon boundaries, including numerous putative subspecies. Phylogenetic analyses of restriction-site-associated DNA sequences (RADseq) allowed new insights into its evolution and taxonomy, enhancing understanding of basal relationships, geographic patterns, taxonomic boundaries, and potential new species.

Methods

A total of 157 individuals in 71 populations across all 15 putative taxa of Camassia and 42 outgroup individuals in 21 populations from Hastingsia and Chlorogalum were sampled and genomic libraries were generated using the modified single-digest RADs
