Specimen Data

Providing access to specimen data from Pacific Northwest herbaria is a primary function of the Consortium's web site. All types of herbarium collections are represented, including vascular plants, bryophytes, liverworts, hornworts, algae, lichens, and fungi.

Approximately 2.2 million (61%) of the 3.6 million specimen records held by PNW herbaria have been databased and/or imaged; the majority of these records are available here through the PNW Herbaria web site.
