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

The 50,300 specimens document the distribution and natural variation of vascular plants and bryophytes, primarily from Kansas, adjacent states, and North America, but also 61 foreign countries. Over 11,000 new collections have been added the past decade, mostly comprising student collections. Ca. 1500 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 bryophytes are data based on the Consortium of Bryophyte Herbaria (https://bryophyteportal.org) or this website. Ca. 40 percent of the specimens include phenological data; over 15 percent are vouchers for published research; and ca. 44 percent include geocoordinates. Significant collections include H.S. MacKee from New Caledonia, T.M. Sperry from the Dem. Rep. of the Congo, and H. Tuomisto from Peru. Ornamental (non-native) occurrences mostly are not data based. Student and volunteer curatorial assistance, as well as generous financial support from the National Science Foundation (CSBR 1756276), is gratefully acknowledged.
