44 FOSSIL FLORA OF THE JOHN DAY BASIN, OREGON. [buu„ 204. 



A .sing'le broken spociuien is all that I now refer to this form. It 

 was clearly a large thick leaf, with prominent deeply impressed ner- 

 vation. It is entire in the lower portion, but from the size and 

 disposition of the secondaries in the middle of the blade it was appar- 

 ently lobed or toothed above. Its length was about 12 cm. and the 

 width about 6.5 cm. It is doubtfully referred to Quercus. 



Locality. — Cherry Creek, Crook County, Oregon. Collected by 

 Knowlton and Merriam, July, 1901 (U. S. Nat. Mus., No. 8555). 



Quercus paucidentata Newb, 



QuERcrs PAUCIDENTATA Ncwb., Proc. U. S. Nat. Mus., Vol. V, p. 505, 1883; Later 

 Extinct Floras, p. 76, PL XLIII, fig. 1, 1898. 



It is with some misg'iving that this species is permitted to stand. It 

 is based, as Newberry says, on a single example,, the onlj^ one ever 

 found. It is in all probability a large leaf of Q. affinis^ but rather 

 than complicate matters by combining forms without sufficient material 

 I have preferred to keep it distinct. 



Locality. — Bridge Creek, Grant County, Oregon. Collected by Rev. 

 Thomas Condon (U. S. Nat. Mus., No. Y059). 



Quercus drymeja linger. 



Quercus drymeja linger. Lesquereux, Cret. and Tert. Fl., p. 245. PI. LTY, fig. 4, 

 1883. 



Lesquereux has figured a single leaf of this form, and the Bendire 

 collection contains another example. Neither of these is perfectly 

 preserved, but they seem to difl'er from other allied forms. It may 

 be, however, that they are ver}^ large leaves of Q. consimilis Newb. 



Locality. — Bridge Creek, Grant County, Oregon. Collected by 

 Maj. Charles E. Bendire (U. 8. Nat. Mus.,^Nos. 9231, 9328). 



Quercus simplex Newb. 



Quercus simplex Newb., Proc. U. S. Nat. Mus., Vol. V., p. 505, 1883; Later Extinct 

 Floras, p. 78, PI. XLIII, fig. 6, 1898. 



As stated by Newberry the collections from Bridge Creek always 

 contain a large number of leaves of this species. They are of the same 

 size and shape as leaves of Q. consimiUs, and only differ in being 

 entire margined, and Newberry questioned as to whether they might 

 not be only a varietal form of that species. As none of the specimens 

 that have passed under my observation show any such gradation, it 

 may be taken as estal)lished that they are distinct. 



Locality. — Bridge Creek, Grant County, Oregon, collected by Rev. 

 Thomas Condon (U. S. Nat. Mus., No. 7058a) and Maj. Charles E. 

 Bendire (U. S. Nat. Mus., Nos. 9219, 9227, 9238, 9249, 9252, 9264, 

 9283, 9289, 9295, 9300, 9302, 9312, 9316, 9332, 9336, 9369, 9380, 9383). 

 Officer's ranch, lower end of Butler Basin. Collected by Dr. John 

 C. Merriam, July 22, 1901 (IT. S. Nat. Mus., No. 9210).
