The MBLWHOI Library Herbarium (SPWH), formerly the Marine Biological Laboratory Herbarium, documents the flora of Cape Cod, Massachusetts, and adjacent islands. The collection, dating back to the 1850s, consists of approximately 7,000 vascular and 2,000 non-vascular plant specimens. The non-vascular collection consists primarily of marine algae of Cape Cod and the Islands. The Digital Herbarium is a fully searchable database of specimen images and data serving as an online compendium of the marine, freshwater and terrestrial flora of Cape cod and the Islands.

The MBLWHOI Library Herbarium is housed at the Data Library & Archives, McLean Laboratory, Woods Hole Oceanographic Institution Quissett Campus. Care of the Herbarium is the responsibility of the Botanical Club of Cape Cod and the Islands. Visits to the Herbarium are available by appointment only.
