Description: The specimen, which contains well-preserved branches 

 with leaves, a branch with leaves and a pistillate cone at the end, and 

 two staminate cones, is found on a gray sandstone (?) collected in 

 1903 by Earl Douglass at the head of Jack Creek Canyon, Madison 

 Mt., Montana. Mr. Douglass gives the horizon as "Dakota?" 

 There is, I think, no doubt that the horizon has been correctly identi- 

 fied by Mr. Douglass. Since the species is found in the United States, 

 Canada, Greenland, and Europe, and apparently ranges from the upper 

 part of the Jurassic through the whole of the Cretaceous, it is im- 

 possible to say with positive certainty, from such an isolated specimen, 

 whether it belongs to the Dakota, or to some other formation.
