Nelumbium sp. 

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



A fragmentary leaf from the Similkameen river at Nine-mile creek is referred by 

 Sir William Dawson to the genus Nelumbium. It may be identical with the next. 



Nelumbium pygmceum, Dn. 



Bib : Trans. R.S.C., VIII, 1890, iv, 87 ; VIII, 1902, iv, 68. 



The original specimens of this plant were first found one mile above Princeton in the 

 Tulameen river, as recorded by Sir William Dawson. In 1902 additional specimens were 

 recorded by Penhallow from the Horsefly river, while yet other specimens were brought 

 to light in the 1906 collections from the Similkameen river. 



Nelumbium saskatehuense, Dn. 

 Bib: Geol. Surv. Can., 1887 : Trans. R.S.C., V, 1887, iv, 35. 



There is only one record of this species from the Red Deer river, in 1887. 



Neuropteris civica, Dn. 



Bib: Trans. R.S.C., I, 1895, iv, 141. 



The only record of this fern is contained in Sir William Dawson's account of Eocene 

 plants from Burrard inlet, British Columbia. 



Nordenskioldia borealis, Heer. 



Bib : Geol. Surv. Can., 1888-89 ; Trans. R. S. C , VII, 1889, iv, 71 : Geol. Surv. Can., 1875-76 : 

 Lesq., FI. Dak. Gr. 1892, 219 ; Fl. Foss. Arct. II, 65. 



The first Canadian records for this plant in 1875 show its occurrence in the Tertiary 

 beds of the Quesnel river. In 1889 Sir William Dawson again recorded its occurrence in 

 the Miocene of Great Bear river. Of its further distribution in Canada nothing is at 

 present known. 



In the United States, Lesquereux has noted its occurrence in the Dakota group of 



Nyssidium ? sp. 

 Bib : Geol. Surv. Can., 1875-76. 



The single specimen referred with hesitation to this genus, by Sir William Dawson in 

 1875, was obtained from the Quesnel river, but it possesses little or no value for strati- 

 graphical purposes. 



Onoclea sensibilis, Newb. 



Bib: Geol. Surv. Can., 1887 : Trans. R. S. C, IV, 1886, iv, 19-34: Lat. Ex. Fl., 1868, 39; 

 Cret. and Tert. Fl,, 1878, pi. VIII, IX. 



The first Canadian record for this fern is from the Lignite Tertiary of Porcupine creek 

 in 1886. In 1887 Sir William Dawsou also observed it in the collections from Red Deer 

 river; and in 1906 three fragments were obtained from the Horsefly river. 



Lesquereux had already noted its occurrence in the Fort Union group of Fort Union 

 North Dakota.
