otherwise altered to make their relationship clear. Such were noted by Sir William Dawson 

 in collections from the Tranquille and Coldwater rivers in 1890, and similar remains have 

 since appeared in collections from Quilchena. and from both the Tulameen and Horsefly 

 rivers. 



Sequoia angustifolia, Lesq.

Sequoia angustifolia is a very well characterized species which Lesquereux has observed 

 in the Green River group of Elko station, Nevada; at Biack Buttes, Wyoming, and in the 

 Miocene of Florissant, Colorado, and Corral Hollow, California. He directs attention to the 

 close resemblance it bears to Torrey californica. 



In Canada it has been found sparingly at Quilchena, and at the Similkameen, Horsefly 

 and Tulameen rivers. So far as present information permits of such a conclusion, it seems to 

 centre at the Tranquille river, from which numerous specimens have been obtained. 



Sequoia brevifolia, Heer.

 78, pi. LXI, f. 25-27 : U.S. Geol. Surv. Terr., 1874, 2D8 ; 1876, I, 365. 



The Montana formation at Point of Rocks, Wyoming, appears to be the most southern 

 extension of Sequoia brevifolia. From there it ranges north to Greenland, where it appears 

 in the A.tane beds. 



In Canada it has been recorded by Sir William Dawson from Mne-mile creek, on the 

 Similkameen river, and more recently the collections of 1906 have shown it to belong 

 to the floras of the Tulameen and Tranquille rivers, from both of which well preserved 

 specimens have been obtained. 



Sequoia burgessii, Penh.

This species is known through its wood only, and at present there is only one station — 

 the Lignite Tertiary of Porcupine creek, Saskatchewan, as recorded by Penhallowin 1903. 



Sequoia couttsia, Heer. 



Bib : Trans. R.S.C., YIII, 1902, iv, 46, 50: Geol. Surv. Can., 1887: N. Y. Acad. Sc. XII, 

 1892, 30. 



This somewhat rare species of Sequoia has been observed by Hollick in the Cretaceous 

 of Staten island, New York, but elsewhere it appears to be a feature of the Tertiary. The 

 only locality known for the United States is that given above. In Canada it has been 

 observed at the Red Deer river, from which it was obtained by Sir William Dawson in 1887 

 and by Lambe in 1897; and from the Finlay and Omineca rivers as recorded by Sir 

 William Dawson in 1894. It is chiefly represented by the foliage, but the collections of 

 Lambe in 1897 contain fragments of Sequoia cones which are believed to belong to this 

 species.
