54 FOSSIL FLORA OF THE JOHN DAY BASIN, OREGON. [bi'll. 204. 



Uhniis speclosa^ as here emended, may be described as follows: 

 Leaves 10 to 18 cm. in leng-th, 5.5 to 6 cm, in width, pctioled, long 

 ovoid or elliptical in outline, very unequal sided at base, narrow 

 pointed at apex; margins coarsely and doubly serrate; nervation 

 strong, very regular, with a strong midrib and some 15 to 20 pairs 

 of thin, close, parallel secondaries; nervilles numerous, close, mainly 

 percurrent and at right angles to the secondaries. 



The fruit probably of this species is figured and descril)ed by 

 Newberry. 



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

 Rev. Thomas Condon (U. S. Nat. Mus., Nos. 7005, 7066, 7067, 7068) 

 and Maj. Charles E. Bendire (U. S. Nat. Mus., Nos. 9217, 9367).

2-4 and 7), 1898 (1899). 



Leaves membranaceous in texture, lanceolate in outline, narrowed, 

 and very unequal sided at base, long and slender pointed at apex; 

 margin coarsely and irregularly doubly serrate, the primary teeth 

 large, of quite regular size, the other teeth smaller and quite irregu- 

 lar; midrib rather thin, perfectly straight; secondaries about 12 or 

 15 pairs, parallel, at an acute angle and ending in the larger teeth; 

 nervilles numerous, tine, mainly broken, producing a large block net- 

 work between the secondaries. 



This species is founded on a considerable number of leaves besides 

 the ones figured by Newberry under f/! sjMci(^sa. One of the most per- 

 fect has been figured here. This is very narrowly lanceolate, 10 cm. 

 in length and only a little over 3 cm. in width. The petiole is about 

 5 mm. long. Other examples are only about 6 cm. long and 2.5 cm. 

 wide, and this is the usual size. 



As pointed out under 17. speciosa, this species may ))e distinguished 

 by its much smaller size, much narrower shape, and more oblique base. 

 In fact, it approaches closer to V. californica^'' in size and shape than 

 to U. speciosa. It differs from U. californica in having larger, doubly 

 dentate teeth, those of the former species being small and only simply 

 dentate.
