Since it was founded about 1870 by Thomas H. Macbride, the herbarium of the State University of Iowa has grown steadily until it now contains approximately 143,000 mounted or otherwise properly accessioned plant specimens. According to the best figures available for other herbaria (Jones and Meadows, 1948), our herbarium ranks about thirty-fifth in size in the United States or fourteenth in size among herbaria of state universities or state colleges.
