Illustrated U.S. Map From 1932 Shows the Medicinal Plants Native to Each State
Renowned for the rarity of its cartographic treasures, the David Rumsey Map Collection is a one-of-a-kind organization. Over half of its 150,000 historic documents—including one of the world's largest maps—has been digitized, allowing the public to explore the charted world like like never before. One recent addition to this virtual library is the Medicinal Plant Map of the United States, a vintage guide to each state's pharmaceutical flora.
