The OSU herbarium is currently closed while we pack up for a move back to a renovated space. We are currently occupying a temporary location just off campus until summer 2022, when we will be moving back to Cordley Hall. Please contact us before sending any specimens or samples to make sure that we can receive them. 

Due to our space constraints at this temporary location, visiting the herbarium is by appointment only for the time being. Please contact our curator James Mickley to arrange a visit.

If you're driving to our building, there are three entrances off the road. The first two, with the big Botany & Plant Pathology sign, go to the main door (see below). The herbarium is much closer to the third entrance and the side door, so we recommend parking there. There is plenty of free parking in the lots surrounding the building. 

The CTS #8 Bus stops across from our building every 1-2 hours (1 stop west of "F"). Additionally, the CTS #3 bus stops a short walk away on Technology Loop every half hour (2 stops north of "B")
