About The Author
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!
