Epiphytic Fern Hymenophyllum jamesonii

Hymenophyllum jamesonii, an epiphytic fern of neotropical rain forests, has berry-like clusters of sporangia where reproductive spores are produced.

Eric Schuettpelz, a postdoctoral fellow in biology at the time, and Kathleen Pryer, an associate professor at Duke University, integrated genomic data from 400 living fern species with information from the fossil record to construct a time-calibrated family tree for ferns.

Schuettpelz and Pryer received support from the National Science Foundation. To learn more, see the Duke news story Ferns Took to the Tress and Thrived.
