Pittsburg State University, Theodore M. Sperry Herbarium (KSP)

The ca. 42,000 specimens document the distribution and natural variation of vascular plants and bryophytes, primarily from Kansas, adjacent states, and North America. Ca. 4,000 specimens are backlogged, mostly from North America but also ca. 500 from Madagascar and many hundreds of bryophytes. Many specimens are unicates. Important additional holdings from abroad include the Democratic Republic of the Congo, Peru, Myrtaceae (mostly Madagascar and New Caledonia), Poaceae (worldwide), and 26 isotypes. Ca. 6300 collections of North American bryophytes are data based on the Consortium of North American Bryophytes website (https://bryophyteportal.org) or this website. Over ten percent of the collections are vouchers for published research. Significant collections include H.S. MacKee from New Caledonia and H. Tuomisto from Peru. Ornamental (non-native) occurrences mostly are not data based. Student and volunteer curatorial assistance, and well as generous financial support from the National Science Foundation (CSBR 1756276), are gratefully acknowledged.
