The 52,750 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. 800 specimens are backlogged, mostly from North America but also some 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 here or at the Consortium of Bryophyte Herbaria (https://bryophyteportal.org). Some collections of fungi and algae used primarily in teaching will be datasased in the future. 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 and financial support from the National Science Foundation (CSBR 1756276) are gratefully acknowledged.
