I am particularly interested in macroevolutionary patterns and characters that diagnose large clades of ferns and lycophytes. My field work is centered in Mexico, Colombia, and Papua New Guinea. I am based in the Pringle Herbarium (VT) at the University of Vermont. If you have any ferns that you want identified, please send them to me!
To wrap up our special issue, we have a paper by Dave Barrington on polyploid fern biogeography. Dave provides insights on the last 50 years of this field, along with thoughts for future research. https://doi.org/10.1640/0002-8444-110.4.233
