About the vascular plant type collections

We have imaged and databased all of our vascular plant types and a portion of our bryophyte, lichen, and fungi types.

WTU's vascular plant type collections contain about 1,200 specimens, and include much type material from such early Pacific Northwestern collectors as Cusick, Leiberg, Elmer, Heller, Howell, Flett, Abrams, Blankinship, Macbride, Sandberg, and Aven Nelson, as well as more recent collectors such as St. John, Peck, Maguire, Eyerdam, English, Ownbey, Cronquist, Holmgren, Constance, and Detling.

Many of our vascular plant types came to the herbarium with the incorporation of J. W. Thompson's private herbarium in 1943. J. W. Thompson made a consistent effort to visit type localities of as many northwest taxa as he could; as a result, the herbarium is particularly rich in topotypes. Topotypes, however, are stored with the general collections and are not accessible through this page.

Approximately 86% of the vascular types come from the USA, 3% from Mexico, and 2.5% from Canada. 26% come from Washington, 20% from California, 10% from Oregon, and 8% from Idaho. 5% of our types are holotypes, and 68% are isotypes.

A grant from the Mellon Foundation allowed us to capture high-resolution (600 dpi) scans of our vascular plant types.
