Fern and Lycophyte Collections at the BRIT Herbarium

Taxonomy and Evolution of Ferns and Lycophytes Program Currently, we make part of a three-year grant from the United States National Science Foundation to digitize and image the approximately 40,000 specimens of ferns and lycophytes in the BRIT’s herbarium. Pteridoportal is the data portal, where you can access the digitized herbarium specimens. In addition to BRIT, 35 other institutions are […]

Ferns of Colombia

Colombia is estimated to harbor the highest fern diversity of any Neotropical country, with more than 1600 native fern species currently documented.

Taxonomy and Systematics of Ferns and Lycophytes

We are interested in what the species of ferns and lycophytes are and where they occur—something often poorly known for tropical species—and the evolutionary relationships among the species. We generate phylogenetic trees based on DNA sequences that show how the species are related and use the trees as a framework for answering questions about character evolution, biogeography, and evolutionary processes.

Evolution and Development of Leaves

The evolution of leaves changed life on Earth. We study the expression and phylogeny of leaf development genes in lycophytes and ferns to better understand the evolution and development of leaves in the land plants.
