The Pollen & Seed Laboratory

Modern Pollen And Spore Reference Collection

Our lab has one of the largest reference collections in the country west of Harvard, and west of the St. Louis Botanical Garden, Missouri. Our duplicate slides from the U.S. Geological Survey number about 3000, and about 1000 prepared by students focusing on the Pacific Northwest flora. These are vouchered specimens on slides usually with glycerin jelly sealed with plastic rings, but many are in silicone oil. We also have around 3500 modern reference slides prepared by Jane Gray kindly donated to us by the University of Oregon. The collections emphasize the flora of the Northern Hemisphere, but include a broad sampling of the flora of Micronesia.


Modern Pollen and Spore Photo Files

We have photographed specimens for most of the duplicate slides from the U.S. Geological Survey, and have these available at around 1000x magnifications on 3 x 5 cards arranged by family. We estimate the photographs number in the thousands.


Northwest Seed Collection

We have a collection of fruits and seeds from Pacific Northwest trees, shrubs, and herbs. These are organized in small trays with locality information for each specimen.


Paleobotany Library

We have one of the best collections of U.S. Geological Survey paleofloras, primarily ranging in age from Cretaceous to Quaternary, but with an emphasis on floras of Tertiary age from North America. We also have a number of European Tertiary floras including the British series by Reid and Chandler on the London Clay flora.


Reprint collection

Estella has collected reprints from world paleobotanists, ecologists, palynologists and stratigraphers from the 1870s forward, arranged by publication date in file folders in an accessible book case.


Access to the Quaternary Research Center Library (QRC)

The QRC library is a world class collection of books journals and reprints on stratigraphy, paleoecology and paleontology for the Quaternary with a world-wide coverage. It includes reprints from Richard Foster Flint (Yale) and A. Lincoln Washburn, the founder of the Quaternary Research Center (UW).
