Willard Sherman Turrell Herbarium

The Willard Sherman Turrell Herbarium (MU) is a broad collection, both taxonomically and geographically. Holdings include specimens of vascular plants, mosses, fungi, and algae, along with our special collections of type specimens, plant fossils, wood collection, and a microscope slide collection of wood sections, stem sections, root sections, and pollen. Active exchange programs are ongoing with many herbaria worldwide to ensure the continued breadth and depth of the collection.

What is an "Herbarium"?

An Herbarium is an archive of pressed and dried specimens that allow students, researchers, and citizens to observe and study the broad diversity of the plant kingdom often on a global scale and without leaving campus. Though it may look like a dry gray cabinet on the outside, the inside is a treasure of plant material collected from some of the most remote places in the world. We have cones from sugar pine (Pinus lambertiana), that produce the largest cones in North America and tiny alpine plants from Iryan Jaya in the Philippines. We have collections of subtle membranous algae and blue fungi as well as 99% of Ohio vascular flora.

Come visit us!  We’re in 79 Upham Hall (south wing across from the Hefner Museum), west of the Bishop Woods, Oxford Campus, Miami University

Work with Us

Several student Herbarium Assistants are employed each semester to assist with routine activities and grant funded projects.  While working they learn about museum curation techniques, plant taxonomy, and data management, all of which transfer directly to many fields of study.
