Fig. 29. Ithamnns quilchenensis n. sp. 

 Leaves from Quilchena. x 1/1. 



A rhamnaceous fruit, also found in the collection of Ells and Johnston from Quilchena, 

 seems to belong to this specie?. 



In 1875, Sir William Dawson observed in collections from the Que.-nel river a leaf of 

 Rhamnus which he regarded as being near to It. alternoides, Heer. It is probable that this 

 is the same as the one described as R. quilchenensis. 



Rhamnus elegans, Newb. 



Bib : Lat. Ex. FL, XXXV, 117, pi. L. f. 2. 



Rhamnus elegans has been found at Quilchena and the Horsefly river in the collections 

 of 1906, and the specimens cannot be distinguished from Lesquereux's specimens derived 

 from Belmont, Colorado. In assigning the horizon to this locality there appears to be some 

 confusion in the designation. The text refers them to the Cretaceous (Laramie), while the 

 plate description gives them as Eocene. 



Rhamnus eridani, Ung. 



Bib : El. Eoss. Arct., I, 123, 153, pi. XLIX, f. 10 : El. Tert. Helv., Ill, 81, pi. CXXV, f. 16 : 

 Lat. Ex. El. XXXV, 118, pi. XLVIII, f. 7: Proc. IJ. S, Nat. Mus., XI, 1888, 25. 



Several fine specimens of Rhamnus eridani were obtained from the Tranquille river in 

 1906,the only locality in Canada where they have so far been found. This species is never- 

 theless known to the Miocene of Bridge creek, Oregon ; and to the Atane beds of northern 

 Greenland, although very sparingly distributed in all localities. 



Rhamnus gaudini, Heer. 



Bib : El. Tert. Helv., Ill, 79 : pi. CXXIV, f. 4-15 ; CXXV, f. 1, 7, 13 : Bost Jn'l Nat. Hist. 

 VII, 1863, 520. 



Rhamnus gaudini is a species which appears to present very great variation in size and 

 shape. This species was originally founded by Heer on the basis of specimens collected by 

 M. Gaudin from the neighbourhood of Lausanne.
