Botany And Herbarium
Botany + Herbarium Collections
The WTU Herbarium's total holdings number more than 660,000 specimens of vascular and nonvascular plants, fungi, lichens and marine algae with the oldest specimens dating to the late 1800s.
The Herbarium collections maintain a regional focus on the Pacific Northwest, covering Washington, Oregon, Idaho, Montana, Alaska, British Columbia and the Yukon Territory. Other significant collections come from California, the rest of Western North America and the Northern Pacific Rim.
Approximately 375,000 specimens from the WTU Herbarium collection are accessible through this database. 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.
