Corral Hollow, Oregon, and Table mountain, California. In the more recent collections made 

 by Lambe in 1906 the same species has been derived from the Tranquille and Horsefly 

 rivers, and from the number of specimens obtained it would appear to have been an abundant 

 species. Present information, however, would seem to indicate that it is a northern, rather 

 than a southern type. 



Sapindus sp. 



Bib: Geol. Surv. Can., 1887; 1877-78. 



In 1877, Sir William Dawson reported what he believed to be a sipecma oi Sapindus from 

 N"ine-mile creek on the Similkameen river, and again in 1887 what seemed to be the 

 same form was reported from the Red Deer river. The species could not be identified, but 

 Sir William Dawson was of the opinion that its aflinities were with S, angustifolius, Lesq. 



Sapindus affinis, Newb. 

 Bib: Trans. R. S. C, IV, 1868; Lat. Ex. Fl., 1868, 51. 



Sapindus affinis was first noticed by Newberry in the Fort Union group of Gladstone, 

 Dakota. It was subsequently observed by Sir William Dawson in the Lignite Tertiary of 

 Porcupine creek and Great valley, Saskatchewan. No other localities have been recorded. 



Sassafras sp. 



A fragmentary leaf was obtained by Ells and Johnston from Quilchena, in 1 904. It is 

 too incomplete for satisfactory identification, but appears to be a species of Sassafras. 



Sassafras burpeana, Dn. 

 Bib : Trans. R. S. C, III, 1885 ; IV, 1868. 



The only localities known for Sassafras burpeana are those recorded by Sir William 

 Dawson from the Lignite Tertiary of Calgary, Alberta, and Porcupine creek, Saskatchewan. 



Sassafras selwyrdi, Dn. 

 Bib : Geol. Surv. Can., 1879-80, 53 A : Trans. R. S. C, IV, 1886, iv, 28. 



So far as known, Sassafras selwynii is wholly characteristic of the Lignite Tertiary of 

 Roche Percee, Souris river and Porcupine creek, Saskatchewan. 



Scirpus sp. 

 Bib: Trans. R. S. C, IV, 1886. 



Dawson records two forms of leaves from the Lignite Tertiary of Porcupine creek, which 

 he regards as distinct species of Scirpus, but he does not attempt to describe them specifically. 



Sequoia sp. 

 Bib : Trans. R. S. C, VIII, 1890. 



In many of the Tertiary collections there are found fragments of cones and infiorescence 

 which appear to belong to some species of Sequoia, but they are too much fragmented and
