Colorado State University, Charles Maurer Herbarium (CS)

The Charles Maurer Herbarium Collection is the third largest collection of vascular plants (> 104,000 specimens) and is the oldest herbarium (began in 1883) in the southern Rocky Mountain region. Important collections include those by J. Ackerfield, J. Cassidy, J. H. Cowen, C.S. Crandall, and H.D. Harrington. The herbarium has an excellent representation of the Colorado flora as well as the flora of the southern Rocky Mountain region. These herbarium specimens were the primary bases for the Colorado floras published by Rydberg (1906), Harrington (1954), and Ackerfield (2015).
