The CHAS Botany Collection focuses on vascular species of North America, particularly the Midwest/Great Lakes region, from 1834 to the present. There are also a small number of lichen and bryophyte specimens, as well as vascular species from South America and Europe. Over 15,000 specimens have been digitally inventoried and 2,000 have been imaged. The un-digitized backlog is estimated to be approximately 5,000 sheets. Notable collectors include: Henry H. Babcock, H. R. Bennett, A. Chase, W. P. Conant, George B. Grant, F. H. Hosford, H. F. Jaeger, Anna Pederson Kummer, C. G. Lloyd, W. S. Moffatt, E. L. Moseley, Walter L. Necker, E. Palmer, R. S. Schmidt, E. Stimpson, F. A. Swink, L. M. Umbach, H. Van Heurck, Dora Wilken, J. Wolfe, Elizabeth Emerson Atwater, W. W. Calkins, and Herman Silas Pepoon.

http://vertnet.org/resources/norms.html Rooted in Chicago, Illinois, the Chicago Academy of Sciences was founded in 1857 and was the first science museum in Chicago. Through its Peggy Notebaert Nature Museum, the Academy connects its community to local environments and inspires life-long relationships with urban nature. The museum collections and archives contain natural history collections in the disciplines of botany, entomology, geology, herpetology, ichthyology, malacology, mammalogy, oology, ornithology, and paleontology, as well as cultural collections, audio visual collections, and archives. These materials range from the 1830s to the present and are predominantly from North America with a focus in the Midwest/Western Great Lakes region.
