The herbarium of the College of William & Mary (WILLI) was formally organized in 1969, and has since grown to over 80,000 accessioned specimens representing most of our regional vascular plant species. About one half of our collection has been generated by faculty and student research which includes the production of 29 floras and a diversity of other projects. The remainder of the collection has been generated by exchanges with other herbaria, and gifts from individuals and agencies such as the Virginia Natural Heritage. Our focus is on the southeast U.S., with special emphasis on Virginia's Coastal Plain Physiographic Province.
