KNowLTON.] THE FLOKA IN OTHER LOCALITIES 109 



THE FLORA OF THE JOHN DAY BASIN IN OTHER LOCALITIES. 



Before leaving this subject it may be of interest to give a short 

 account of this flora as it has been recorded at several localities beyond 

 the limits of the John Day Basin. This is especially desirable since 

 we now have for the first time a definite knowledge of the geological 

 sequence of the plant-bearing beds in the basin. Up to the date of 

 the publication of Dr. Merriam's paper on the geology of the basin 

 our knowledge of the interrelations of the plant beds has been in a 

 much confused state. This confusion is in large measure due to the 

 fact that no definite localities were given by Lesquereux, they being 

 simpl}^ recorded as "John Day Valley, Oregon," and so it came to be 

 supposed that all species from this area were of the same age. This 

 confusion was helped along by Newberry, who placed Cherry Creek, 

 Currant Creek, and Bridge Creek in the same horizon, which he 

 referred to the Miocene. In his latest publication on the subject 

 (Proc. U. S. Nat. Mus., Vol. XI. pp. 13-24) Lesquereux referred the 

 beds at Cherr}^ Creek to the Laramie and the Van Horn's ranch deposits 

 to the Miocene, but he made no attempt to give more definite localities 

 for the forms mentioned in his earlier reports. It was possible to set- 

 tle the exact locality of these species only by a careful study of the 

 t^^pes, which are the property of the University of California. This 

 investigation, as already set forth, has been made, and the results are 

 incorporated in the foregoing pages. But the confused condition of 

 our knowledge of this flora has made its impress on determinations of 

 the plants whenever they have been found beyond the limits of the John 

 Day Basin. These outside floras will be passed in review and the 

 attempt will be made to adjust them to accord with our present fuller 

 knowledge of the type section. 



So far as I now know, the first recognition of the flora of the John 

 Day Basin be3"ond the original limits was made by m3'self in a 

 "Report on fossil plants from near EUensburg, Washington," which 

 was published in 1893 as an appendix to Bulletin 108 of the United 

 States Geological Survey, by Prof I. C. Russell, entitled "A Geological 

 Reconnoissance in Central Washington. " Ten species were enumerated 

 in this collection as follows: 



Salix varians Gopp. Ulmus pseudo-fulva Lesq. 



Pupnlus glandulifera Ileer. Platanus dissecta Lesq. 



Populus Russelli Kn. Platanus aceroides? (Gopp.) Heer. 



Alnus? sp. Paliurus folomlji Heer. 



Ulmus californica Lesq. Magnolia lanceolata Lesq. 



Some of these forms were recognized by Lesquereux as occurring 

 at Van Horn's ranch, although they have not all been admitted in the 

 present paper. Populua (jkuiduUfera was based on a single example,
