Stop 11

Continue walking into the courtyard of Building 2 and enjoy the numerous varieties of rhododendrons and azaleas. A Ginkgo tree (Ginkgo biloba) with the fan-shaped leaves is located in the center planter. The Ginkgo’s history goes back to at least the early Mesozoic Era (starting about 240 million years ago); this is the only surviving species of this entire plant order. Under the Ginkgo is a small plaque to Roland Brown, a USGS paleobotanist who studied fossilized plants.
