Botany And Herbarium
Botany + Herbarium Collections
The Herbarium's total holdings number more than 660,000 specimens of vascular and nonvascular plants, fungi, lichens, and marine algae. The oldest specimens in the collections date to the late 1800s.
The Herbarium collections maintain a regional focus on the Pacific Northwest, which for our purposes includes Washington, Oregon, Idaho, Montana, Alaska, British Columbia, and the Yukon Territory. Other significant holdings come from California, the remaining areas of Western North America, and the Northern Pacific Rim.
Over 400,000 specimens from the Herbarium collection are accessible through this database and the Consortium of Pacific Northwest Herbaria website. For most vascular plant specimens, only label data are available. Both specimen label data and images are available for most nonvascular plant, fungal, lichen, and marine algae specimens.
