Phylogenomics and historical perspectives in the fern genus Elaphoglossum (Dryopteridaceae).

Elaphoglossum  is one of the most species-rich genera of ferns, with about 600 currently accepted species. The genus is widely distributed in both the New and Old World tropics, but most of its species occur on the mountains of the neotropics, especially in the Andes and the mountains of Panama, and Costa Rica. In these regions,  Elaphoglossum  is the most diverse fern genus and a prominent component of middle- and upper-elevation forests. Over the last 50 years, much has been learned about  Elaphoglossum. Hundreds of new species have been described-including a new fossil, and many insights have been made into morphological evolution. Also, an infrageneric classification have been proposed, several clade-based taxonomic revisions have been published, and perhaps most important, several plastid phylogenies have been published that provide a framework upon which to hang this new information. Here, we present another step in the study of  Elaphoglossum: a target-capture dataset of about 300 low-copy nuclear loci for 173 species from around the world. This talk will reflect upon what has been learned about  Elaphoglossum  over the last half century and how new insights from phylogenomic data are shaping current and future study of this extraordinary genus and tropical ferns in general.
