Tebiwa Herbarium (TBW)
The Tebiwa Herbarium
144 Ross Fork Creek Road #12
Pocatello, ID 83202
U.S.A.
Size:
385 specimens 
Description:
The Tebiwa Herbarium was founded in 2002 by the Davis Family of the Fort Hall Indian Reservation. Tebiwa is a Panakwate (Bannock) term for "one's own country". The focal point of the Tebiwa Herbarium is to establish a comprehensive collection of vascular plants, lichens, bryophytes, and fungi utilized and appreciated by the Davis Newe family and ancestors. The Newe are the Indigenous peoples whose ancestral homeland spanned portions of the Snake, Yellowstone, Bear, and Salmon River watersheds and beyond. Historically, the Newe were referred to as “Snake Indians”, Shoshone, or Bannock by early Euro-American colonists. Currently, the Tebiwa Herbarium houses 389 specimens representing 329 vascular plants, 24 lichens, 24 bryophytes, 11 fungi and 1 liverwort. Although most of the specimens are from the state of Idaho, it also includes collections from Washington, Wyoming, Montana, Oregon, Arizona, Utah, Texas, and Loreto, Peru. 
Specialty:
At the Tebiwa Herbarium we strive to include Panakwate (Bannock) and Sosoni (Shoshone) language names and uses on specimen labels. The Herbarium also houses collections of vascular plant associates of the peyote cactus (Lophophora williamsii), as well as vascular plants and biological soil crusts from Palouse Prairie in northern Idaho and southeastern Washington. Access and use of the Tebiwa Herbarium is by appointment only.

Size:

Description:
The Montana State University Northern Herbarium represents a new repository for plants growing in the diverse habitats associated within the north central and eastern plains of Montana. In addition to grass- and shrub lands, we house specimen vouchers from localized mountain areas that rise above the plains (e.g., Sweetgrass Hills, Bears Paw and Little Belt Mountains). Plants collected from prairie potholes and limestone outcrops, as well as those from cottonwood dominated riparian areas and gumbo bluffs associated with the Missouri River Breaks, are included in the collection. Voucher age ranges from the early 1900’s to the present and some of these represent plants collected from more well-known regions, e.g., Yellowstone, Rocky Mountain, and Glacier National Parks. 
Specialty:
Flora of the north central and eastern plains of Montana.
