A phylogeny of the evening primrose family (Onagraceae) using a target enrichment approach for 322 nuclear loci.

The evening primroses (Onagraceae) are a large family of approximately 655 species in 7 tribes and 17 genera. A majority of these species are from the New World, especially western North America. Comparative studies in this group are focused on the striking variation in floral morphology and floral scent, pollination syndrome, embryology, and cytology, among other characteristics. However, these efforts are limited by the lack of a comprehensive, well-resolved phylogeny. Previous molecular studies using relatively few nuclear and chloroplast markers strongly support the monophyly of the family, the sister relationship of the families two largest tribes (Onagreae. 262 spp., and Epilobieae, 172 spp.), and the paraphyly of the large genus Oenothera as defined at the time. However, several relationships within the family remain to be resolved, including the placement of two sections recently sunk within Oenothera: Calylophus and Pachylophus. Here, we use a target enrichment approach to reconstruct the phylogeny of Onagraceae using 322 highly conserved, low-copy nuclear loci assembled with the HybPiper pipeline. We present a phylogeny for Onagraceae with taxa sampled throughout the family, including a majority of taxa in the tribe Onagreae. This phylogenetic resource will augment ongoing projects focused on the ecology, genomics, and coevolutionary dynamics of this important group.
