In his account of the Flora of the John Day basin Dr. Knowlton described a willow 

 obtained from the Miocene of Van Home's ranch, under the name of Salix perplexa. In the 

 1906 material from Quilchena, British Columbia, there were two leaves devoid of venation, 

 but in their general size and form they presented a closer approximation to S. perptexa than 

 to any other species, and are so referred. 



Salix raeana, Heer. 



Bib : Fl. Fossr:a^ct., I.,102, 139 : Trans. R.S.C., IV, 1886. 



Salix raeana, although not an abundant species, ranges from the Lignite Tertiary of 

 Porcupine creek, Great valley and the Mackenzie river, to the Miocene of the John Day basin, 

 Oregon, and Cook inlet, Alaska. 



Salix iulameenensis n. sp. 



A single example of a fruit was found in the 1906 collections from the Tulameen river 

 (Figure 31). It bears a very close resemblance to the fruit of a willow and is therefore 

 referred to a new species, S. tulameenensis. It answers to the following description : — 



Fruit ovoid, 3. 5 mm broad, 41 mm long ; short stalked ; prolonged at the apex into a 

 much attenuated beak.

In 1895, Sir William Dawson obtained specimens o{ Salix varians from the Tertiary, beds 

 of Vancouver. There can be little doubt of theldentity of his specimens with those originally 

 obtained by Heer from Oeningen ; and with Lesquereux's specimens from the Miocene of
