Please note that a digitization project is underway; loans may take longer to process and access to the vascular plant collection may be interrupted during this time.

The Harvard University Herbaria include six collections and more than five million specimens of algae, bryophytes, fungi, and vascular plants. Together they form one of the largest university herbarium collections in the world, and the third largest herbarium in the United States. With their state-of-the art research laboratories and world class libraries, the HUH have been a centerpiece of biodiversity science since the early 1800s.
