We currently house nearly 7000 specimens, mostly representing Central Arkansas. Major collectors include the late Hendrix biology faculty member G. Thomas Clark, David M. Johnson who collected here in the 1970s, and a nice set of most of the fern species of central Arkansas collected by Don Crank in 2010. The herbaria also contains small curated collections of bryophytes, lichen, and macroalgae, databased and searchable through bryophyteportal.org, lichenportal.org, and macroalgae.org.
