On this side of the Atlantic it appears to occur with great rarity, the only localities at 

 present known being at Birch bay, Washington, and Quilchena, British Columbia, as more 

 recently determined through the collections of 1906. 



Rhus roscBJolia f Lesq. 

 Bib : Geol. Surv. Can., VII, 1894, 231 B : Tert. Fl. 1878, 293. 



Lesquereux recorded this species from the Green River group of Florissant, Colorado, 

 in 1878. Since then it has been noted by Sir William Dawson at Coal brook, British 

 Columbia, but there are no further records of it. 



Sabalites camjibellii (Newb.) Knowlton. 

 Bib : Trans. E. S. C, 1, 1895 : Tert. Fi., 1878, 113. 



As recorded by Sir William Dawson, Burrard inlet is the Canadian locality at present 

 known for Sabalites campbellii, although it is somewhat abundant in the United States, 

 being found in the Denver group of Golden, Colorado ; the Fort Union group of the Yellow- 

 stone river, Montana, and the Laramie of Raton mountains and Gelirungs, Colorado. 



Salix Integra, Goepp. 



Bib : J.S. Gleol. Surv. Terr., 1873, 397 : Tert. Fl., 1878, 167 : T.R.S.C, I, 1895. 



This somewhat rare species of willow is known to the Canadian Tertiary from Burrard 

 inlet, as recorded by Sir William Dawson in 1895. In the United States it has been recorded 

 by Lesquereux from Black Buttes, Wyoming ; Golden, Colorado and Corral Hollow, California. 



Salix kamloopsiana, Dn. 

 Bib; Trans. R.S.C., VIII, 1890, iv, 90. 



The only record for this species is that given by Sir William Dawson in 1890, when it 

 was obtained from Kamloops, British Columbia. The very close resemblance which it bears 

 to S. varians suggests that it may be only a form of that species, more particularly as it has 

 been found in no other collection. 



Salix laramiana, Dn. 



Bib : Trans. R.S.C., IV, 1886, iv, 28 : Geol. Surv. Can., 1887. 



Salix laramiana was first recorded by Sir William Dawson from the Lignite Tertiary 

 of Porcupine creek in 1886, but was subsequently reported from the Red Deer river. No 



other localities are known. 



Salix orbicularis n. sp. 



In the 1904 collection of Ells and Johnston, from Quilchena, there was an imperfect 

 specimen of a small, rounded leaf which appears to be a willow but of distinctive character. 

 It is provisionally assigned a new name, and answers to the following description : — 



Leaf orbicular, devoid of a petiole ; margin entire ; 16 cm wide, ] . 9 cm long. Figure 30.
