Collection Profile for: Northern Kentucky University, John W. Thieret Herbarium (KNK)
The John W. Thieret Herbarium (KNK) at Northern Kentucky University, in Highland Heights, Kentucky, specializes in flora of the southeastern and midwestern US. Most of our approximately 30,000 collections are from Kentucky, Louisiana, Mississippi, and Ohio. In addition, we have many specimens from the Canadian Arctic, which was one of Dr. Theiret's regions of interest. Due to the combined efforts of Dr. Thieret and Dr. Naczi, we also have especially good collections of sedges (Cyperaceae) and grasses (Poaceae).
