Academics require good libraries, but many botanists need more than books -- they need actual plants. The John W. Thieret Herbarium serves that purpose. It is a library of approximately 40,000 pressed and dried plant specimens.
To document wild & cultivated flora
To facilitate floristic research
To educate students & the public
For these purposes, the herbarium seeks to maintain, provide access to, and augment its collections of these plants. The staff is committed to serving the scientific community and to providing outreach by sharing collections and botanical expertise with those not of that community.
The collections are primarily used by researchers, but educational tours for students or interested community groups may also be possible. Contact Dr. Whitson to inquire.
Location: Room SC 101 in the Dorothy Westerman Herrmann Natural Science Center.

Our focus is vascular (mostly flowering) plants of the US, particularly from Kentucky, Ohio, and the Southeast. We also have extensive collections from the Great Basin, the Great Plains, and the Canadian Arctic.
Our collections are particularly rich in wetland and aquatic plants and grasses (the Poaceae), which were specialties of Dr. Thieret, and sedges (the Cyperaceae), which were Dr. Naczi's focus.
