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

The ca. 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. 2500 specimens are backlogged, mostly from North America but also ca. 500 from Madagascar and many hundreds of bryophytes. Many specimens are unicates. Important holdings from abroad include the Democratic Republic of the Congo (T. M. Sperry), Peru (H. Tuomistso), Myrtaceae (H.S. MacKee and others from New Caledonia; Eugenia and Syzygium from Madagascar), Poaceae (worldwide), and 30 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. Student and volunteer curatorial assistance, as well as generous financial support from the National Science Foundation (CSBR 1756276), is gratefully acknowledged.
