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

The 52,650 specimens document the distribution and natural variation of vascular plants and bryophytes, primarily from Kansas, adjacent states, and North America, but also 60 foreign countries. Approximately 12,020 new collections have been added the past decade, mostly comprising student collections. Ca. 1800 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. Tuomisto), Myrtaceae (H.S. MacKee and others from New Caledonia); Eugenia and Syzygium from Madagascar, Poaceae (worldwide), and 30 isotypes. Data for ca. 6300 bryophytes are on the Consortium of Bryophyte Herbaria (https://bryophyteportal.org) or this website. Phenological data (flowering/fruiting) and geocoordinates are present for ca. 45 percent of the specimens; and over 15 percent are vouchers for published research. Student and volunteer curatorial assistance, as well as generous financial support from the National Science Foundation (CSBR 1756276), is gratefully acknowledged.
