Miocene of Hredavatu in the Archipelago of arctic America, and the Mackenzie River basin. 

 In the same collection there were also two seeds so related to one another (figure 22) and

 Two younf; seeds from Quilohena. x 1/1, 



SO associated with the scales as to suggest that they were of the same species and in that 

 position which they had at the time the scale was removed by decay. The absence of wings 

 indicates that the seeds had also been subject to decay, but of such a limited nature as to 

 leave them nearly intact. In a few instances there were perfect seeds (figure 23), these 

 may belong here, but they may also be the seeds of P. lardyana.

In 1890 Sir "William Dawson described under the name Pinus trunculus a group of 

 pine leaves from the Similkameen river, which was not complete. He also refers to the fact 

 that the same type of leaves is to be found at Stump lake and on the Tranquille river. 



In the collections of Mr. Lambe in 1906 there were a large number of pine leaves, 

 especially from the Tranquille river, and many of these could be correlated with Pinus trunculus 

 without any difficulty. From this material it becomes possible to gain a more correct con- 

 ception of the proper dimensions of these organs than could be got from the original, truncated 

 specimens of Sir William Dawson. The specimens from the Tranquille river were especially
