In 1898, Knowlton determined the essential identity of Fagus castanecefolia, Unger, with 

 Castanea ungeri, Heer, and thus combined these hitherto distinctive names in the designation 

 Castanea castanecefolia (Ung.) Knowlton. 



This somewhat well characterized species was first observed in Canada by Sir William 

 Dawson in 1875, in collections from both the Blackwater and the Quesnel rivers. Dawson 

 then expressed the opinion that it was allied to the Forth American species C. pumila. In 

 1902 it was again recognized by Penhallow in collections from the Horsefly river, but it has 

 not been seen in any of the subsequent collections. It is, however, a well known species in 

 the United States where it is found in the Miocene of John Day valley, Oregon, and Corral 

 Hollow, California, as well as in the Eocene of Cherry creek, Oregon. In Alaska it occurs at 

 Port Graham. 



Castanea intermedia f Lesq.

The only representation of this species was found in a small fragment showing the 

 margin of a leaf and a small part of the venation. Some doubt attaches to the identification 

 because of the close resemblance to Qaereus consimilis, which it may be. The specimen was 

 found in the collection from Quilchena, made by Lambe in 1906. Lesquereux's determi- 

 nations show it to occur in the Grreen River group of Middle park, Colorado, and Randolph 

 county, "Wyoming.

 iv, 19-34. 



Since Newberry's recognition of this rather rare species, in the Fort Union group of 

 Montana, it has been recognized by Sir William Dawson in the Tertiary of the Red Deer 

 river, and in the Lignite Tertiary of Porcupine creek and adjacent localities. There is no 

 record of its occurrence since that time. 



Ceanothus sp. 



Bib : Trans. R.S.C., VIII, 1890, iv, 75-91. 



The only record for this undescribed species of Ceanothus is to be found in the account 

 by Sir William Dawson who derived his specimen from the Tulameen river in 1890 

 and from deposits supposed to be of lower Miocene or Oligocene age. Only two other 

 records for American localities have been made for the genus. These are C. meigsii, 

 Lesq., from the eolignitic of Mississippi and Lagrange, Tennessee; and C. cretaceus, I)n.» 

 from the Upper Ci'etacepus of Port McNeill, Vancouver island, with neither of which is there 

 a possible correlation. 



Cercis parvifolia, Lesq. 



Bib: Trans. R.S.C., VIIL 1890, iv, 46 : Cret. and Tert. Fl., 1883, 201. 



The recognition of Cercis parvifolia in the Tertiary beds of Red Deer river in 1902 con- 

 stituted the first observation of this species since Lesquereux obtained it from the Green
