Resolving relationships in Cleomaceae using Hyb-Seq, the Angiosperms353 probe set, and herbaria.

Robust and comprehensive phylogenetic trees for global plant families can be difficult to generate due to complications with field work and access to remote species, but herbarium vouchers provide a powerful resource to counteract these difficulties. Here, we present preliminary data in the ongoing process of generating a revised phylogenetic hypothesis for the plant family Cleomaceae. Cleomaceae is composed of approximately 27 genera and 270 species occurring world-wide, making it difficult to sample comprehensively. Previous research has used morphology and limited genetic data to update various Cleomaceae lineages, but a stable family phylogeny has not been generated. We use herbarium vouchers and high throughput sequencing (Hyb-Seq) combined with the Angiosperms353 probe set to clarify phylogenetic relationships in Cleomaceae. In this talk, we present preliminary findings produced from approximately 200 specimens representing 146 species and 26 genera. We discuss inter- and intra-generic relationships and correlations with geographic distributions. We then outline our future plans to build on this phylogenetic hypothesis. To provide a robust revision of the family, we will ultimately sample ~90% of the species in the family, with a majority of samples coming from herbaria collections.
