Pinus tulameenensis n. sp. 



In the material from the Tulameen river there was one specimen of pine foliage showing 

 four small leaves in a fascicle, (Figure 4). These may be described as follows : — 



Fig. 34. Pinus tulameenensis n. sp. 

 Leaves from Tulameen River, x 1/1. 



Leaves four, very slender, 23 mm. long, 0.30 broad with one nerve? ; apex acute. 

 It is possible that figure 23, referred to P. steenstrwpiana, may belong here. 



Planera crenata, Newb. 



Bib: Proc.U. S. Nat. Mu3., V, 1882, 508: Lat. Ex. Fl., XXXV, 81, pi. LVII, f. 3 : Trans. 

 K.S.C., I, 1895. 



This leaf was first recorded by Sir William Dawson in 1895 from Burrard inlet, British 

 Columbia; and in 1906 it was obtained from the Horsefly river where it was represented by 

 a small fragment only. The only record for the United States is that given by Newberry, 

 who noted its occurrence at Tongue river, Montana 



Planera longifolia, Lesq.

 XXIX, f. 1-3 : XLIV, f. 10; Trans. H.S.C, VIII, 1890, iv, 85 ; VIII, 1902, iv, 68. 



Planera longifolia is a very well characterized species which was first obtained from the 

 north fork of the Similkameen river in 1896, as recorded by Sir "William Dawson; and in 

 1891 it was obtained from the Horsefly river. 



In 1906 it was found in collections from the Tranquille river, in which it was repre- 

 sented by one fragment only, but numerous fairly good specimens were obtained from the 

 Tulameen river — essentially the same locality as that from which Sir William Dawson's 

 specimens were derived — and it was yet more abundant in material from the Horsefly river, 

 the specimens being characterized by their well defined venation and well defined though 

 never complete margins. 



Both Newberry and Lesquereux have shown that this species is a constituent of the 

 flora of the Green River group of Elko station, Nevada, and Florissant, Colorado. 



Platanus sp. 



Bib : Geol. Surv. Can., 1871-72, 59; 1877-78, 187 B. : Trans. R.S.C, I, 1895. 



In 1871 Sir William Dawson referred to imperfect specimens of leaves from the mouth 

 of the Quesnel river, as of a speciesof Platanus, and also directed attention to the occurrence in 

 9197—10
