Illinois Herbaria
Illinois Natural History Survey Herbarium (ILLS)
University of Illinois Plant Biology Herbarium (ILL)
University of Illinois Crop Evolution Laboratory Herbarium (CEL)
The Illinois Herbaria comprise three collections housed within one facility at the Illinois Natural History Survey that preserve more than 1.3 million specimens of vascular plants, bryophytes, and algae. Combined with the ILL and ILLS Fungaria, the total holdings equal over 1.5 million specimens. This combined collection is the second largest in Illinois and ranks among the top ten largest herbarium collections in the United States.
Although global in scope, the Illinois Herbaria represents the largest collection of Illinois flora in the world. Together they serve as an invaluable resource for research, education, conservation, and the documentation of plant and fungal diversity.
