154 ME80Z0IC FLORAS OF UNITED STATES. 



made are the same. The rock of some of the specimens in both coUections 

 is exactly alike, and many of the plants are the same. There can be no 

 doubt that both of these collections show plants belonging to the same 

 flora. 



In 1901 Mr. F. C. Schrader collected a few fossil plants on the 

 northwest coast of Alaska, about 180 miles northeast of Cape Lisbiu'ne 

 (see p. 146). The locality is between Icy Cape and Wainwright Inlet. 

 A number of the rock specimens show only indeterminable fragments of 

 plants. Four fragments of rock, however, give fossils exhibiting enough 

 character to be determined with some certainty. These fossils belong to 

 the same flora as that shown in the Woolfe and Dumars collections, and, 

 with one exception, are probably all identical with forms found in these 

 two collections. The rock material also which bears Schrader's plants 

 is strikingly like that containing the fossils of the other two collections. 

 Although the amount of material obtained by Mr. Schrader, availalile for 

 comparison, is small, it is sufficient to indicate strongly that it comes from 

 a formation of the same age as that >'ielding the two collections previously 

 made. 



All of these collections have been turned over to me for examination 

 and the present paper gives the results.

"Professor Fontaine considers this specimen too vague for determination. It is, however, quite clear on 

 the stone and Lesquereu.x's figure represents it fairly well. It may stand as a problematical organism. —
