Some years ago, when preparing the manuscript for ni}^ Catalogue 

 of the Cretaceous and Tertiary Plants of North America, I was led 

 from a casual examination of the figures to refer this species to Q. con- 

 similis Newb. and Q. paucidentata Newb. Since that time I have 

 found the long narrow leaves of Q. Breweri in the vicinitv of Ashland, 

 Oregon, and I have also gone carefully over the abundant material 

 from Bridge Creek, which contains a number of finely preserved leaves, 

 and I am now inclined to regard them as distinct from Q. conshnllls. 

 They are undoubtedly close to this species, yet differ in being much 

 longer and narrower. They can be readily distinguished. I have seen 

 and examined the types of this species in the University of California, 

 and I am the more convinced that it is distinct.

Under the above name Lesquereux has figured a number of leaves 

 from Bridge Creek. Thej'^ differ considerablv among themselves, yet 

 may well belong to a single polymorphous species. Nearly all the 

 forms are abundant in any collection from this locality. 



The leaf figured by Newberry as Populuspolyinorpha (loe. cit., fig. 4) 

 is certainh' the same as fig. 6 of PI. LIII in the Cretaceous and Ter- 

 tiary Flora, and 1 have placed it under this species as determined by 

 Lesquereux. It is one of the most abundant forms in all collections.
