For further research on Deborah Griscom Passmore:
A small collection of Passmore's cacti watercolors are in the collections of the Department of Botany, National Museum of Natural History, Smithsonian Institution. They may be viewed online through links available from the Smithsonian Botanical Illustrations Catalog along with a brief biographical note. These watercolors appeared in print in The Cactaceae by Nathaniel Lord Britton and J. N. Rose, published in Washington, D.C. by The Carnegie Institution of Washington, in four volumes, from 1919-1923. Unfortunately, her original illustrations only appear in the first (1919-1923) printing of the four-volume set, and were replaced by photostats of her images or photographs of plant specimens in subsequent printings and editions.
Many of the pomological watercolors created by Passmore during her years with the USDA (1892-1911) may be found within the USDA Pomological Watercolor Collection in the Special Collections of the National Agricultural Library.
Other strawberry images are available online as part of the Papers of George M. Darrow.
Several prints of original Passmore pomology images are on permanent exhibit in the main reading room of the National Agricultural Library. Images include the Calamondian orange, 1909, the Miller raspberry, 1895, and the Steptoe plum, 1894.
