Represented by two frag-ments that are more or less obscure and 

 doubtful. There is also a single fragment obtained by the expedition 

 of the University of California of 1900. 



Zocallty.— Chewy Creek, Crook County, Oregon. Collected by 

 Maj. Charles E. Bendire (U. S. Nat. Mus., No. 2489) and by Merriam's 

 party of 1900 (Mus. Univ. Cal., No. 188).

Leaflet coriaceous in texture, lanceolate, apparently wedge-shaped at 

 base and acuminate at apex; margin irregularly and rather obscurely 

 toothed; midrib very thick, straight; secondaries numerous, rather 

 close, about 2<» pairs, alternate, at an angle of about 45^, somewhat 

 arching upward, camptodrome, arching near the margin and each 

 joining the one next above by a thin branch, with their nervilles on 

 the outside passing to the marginal teeth; nervilles numerous, percur- 

 rent, at right angles to the secondaries; finer nervation producing a 

 close areolation. 



This particular specimen, as noted above, was referred to Tle.r longi- 

 folia Heer, a species from the Miocene of Piedmont, but a com- 

 parison with the figure given by Heer shows that it is undoubtedly 

 different. Tne original seems to have been a much shorter leaf, and 

 while the Oregon specimen resembles it in a general way, there are 

 important differences. The teeth are different, the secondaries more 

 numerous, and the finer nervation is of a totally different character. 



The question of the proper generic reference of this leaf or leaflet 

 is an open one. It is not greatly unlike things that have been vari- 

 ously referred to Ilex, Quercus, and Juglans, but on the whole .seems 

 to have closest relationship with the latter. It will, however, need 

 more and lietter material to settle the matter detinitely. 



Local if I/.— Chewy Creek, Crook County, Oregon. Collected by 

 Maj. Charles E. Bendire (U. S. Nat. Mus., No. 8545, on same stone 

 with 2424). 



Juglans Schimperi^ Lesq. 



Juglans Schimpeki Lesq., Tert.- Fl., p. 287, PL LVI, ligs. 5-10, 1878. 



A single example that seems to lie identical with this species, 3"et as 

 the specimen is broken and is the only one, 1 have preferred to ques- 

 tion it. 



LocaUti/. — Bridge ('reek. Grant County, Oregon. Collected by 

 Merriam's expedition of 1900 (Mus. Univ. Cal., No. 190).
