USDA Plant Introduction Station (Chico, California) Photograph Collection

The USDA Plant Introduction Station (Chico, California) Photograph Collection consists primarily of photographs and negatives of pistachios that were grown in Chico, California. Photographers include W. E. Whitehouse, R. L. Taylor, J. C. Long, C. L. Stone, and Mitchell. Some photographs were taken at the Beltsville, Maryland, area and Washington, D.C., laboratories since specimens were sent there from Chico. Additional subjects include persimmons, walnuts, pears, crabapples, apricots, plums, peach-almond tree, cherries, avocados, guavas, mangoes, annonas, jujubes, oranges, and various vegetables. Many of the photographs were taken on plant exploration trips, such as Whitehouse's trip to Persia in 1929, Dorsett and Dorsett's trip to China in 1924-1925, Dorsett and Morse's trip to China in 1931, and Long and Stone's trip to California in 1936. The collection also includes a set of index cards with plant introduction number, name of plant, type of fruit, where it originated, and other information, such as whether it was growing in quarantine at Bell, Maryland or where seeds were sent.
