Currently, the Bartley Herbarium consists of approximately 55,000 mounted and accessioned specimens, plus several thousand additional unmounted and unaccessioned specimens being processed. Of these, 30, 657 specimens were collected in Ohio, with the remainder being mostly from other parts of the eastern United States. Our Herbarium is the largest in Appalachian Ohio and seventh largest in the state. It is particularly rich in specimens from southern and southeastern Ohio, due to the efforts of Floyd Bartley and subsequent botanists who have been active in the region. It has the largest holding of vascular plant specimens from the unglaciated, Appalachian region of Ohio. The Bartley Herbarium is the main repository for flora projects conducted in this region, as well as the recipient of vouchers from ecological investigations and regional systematic studies of particular plant groups.
