The University of Nebraska at Kearney Herbarium (NEBK) contains ca. 35,000 specimens of vascular plants and approximately 4000 bryophytes and lichens. The collection is mostly regional and representative of the mixed-grass prairies of the Central Great Plains. The organization of NEBK can largely be attributed to the late Ole A. Kolstad who was curator from 1965-1992. Some significant collections are those by H.A. Hapeman (late 1800’s-early 1900’s), W.E. Bruner (1930’s), O.A. Kolstad (1960’s-1970’s), and G.E. Larson (1970’s to date). Grasses (Poaceae), sedges (Cyperaceae), and rushes (Juncaceae) are well represented.
