Not illustrated. 1909 Excerpt: the plant horizon at Harpers station. Two of the species Brachyphyllum n. sp. and Sequoia reichenbachi) are found at Harpers station and two others of the named species Trapa (?) micro, phylla and Diospyrus (?) ficoidea) are found at Black Buttes and Point of Rocks. The latter species are also found in the Fort Union beds, but in the lower horizon. The other named species Asimina eocenica), depending on a single example, has been found in the Denver beds at Golden, Colo., and at Carbon, Wyo.

The associated strata are not exposed in the immediate neighborhood, but about 3 miles to the southwest, near the old stage road crossing Cooper Creek, beds that are certainly higher in position are very fossiliferous, yielding a characteristic Fox Hills fauna, as follows: Micrabacia americana M. and H.
