Geological Survey Bulletin 204 Fossil Flora of the John Day Basin, Oregon

Family GINKGOACEÆ.

GINKGO sp.

Pl. I, fig. 5.

The collection contains a fragment of what appears to be a leaf of Ginkgo, but it is too much broken to make out any of the essential characters. The most that can be said is that it must have been a large leaf as compared with the living species.

Locality.—Mascall beds, Van Horn's ranch, about 12 miles west of Mount Vernon, Grant County, Oregon. Collected by John C. Merriam, July, 1901 (U. S. Nat. Mus., No. 8536).
