KNowi.TON.] DESCRIPTION OF SPECIES. 59 



by a series of broad loops, the one next above; nervilles prominent, 

 oblique to the midril) and main!}' })roken, produeino- large, irregular 

 areas; finer nervilles numerous, very thin, oblique to the stronger ones; 

 ultimate nervation made up of ver}^ minute but regular reticulations. 



This species is represented thus far by only two specimens, the one 

 figured and another much less perfect. The one shown in the plate 

 was about 18 cm. long (13.5 cm. in length is now preserved), and 3.5 

 cm. wide at a point probably a little above the middle. It is impossible 

 to estimate the length of the other specimens, but it is wider, being 

 fully -1.5 cm. wide. The nervation differs slightly, also, the seconda- 

 ries arise at a less acute angle, but otherwise there is no appreciable 

 difference. 



The affinity of the unfigured example seems to be with some forms of 

 Lojurus californlcci Lesq., ))ut it differs in having the secondaries at a 

 more acute angle of divergence and undoubtedl}^ belongs with the leaf 

 figured. It may also be compared with Persea jninctalata Lesq." 



Locality. — Van Horn's ranch, about 12 miles west of Mount Vernon, 

 Grant County, Oregon. Collected b}^ Merriam's expedition of 1900 

 (Mus. Univ. Cal., No. 868).

The material from Cherry Creek obtained in lOOl contains one 

 nearly perfect example and several fragmentary specimens that must 

 belong to this species. The most perfect specimen is slightly larger 

 than the tA^pe, but otherwise there is no appreciable difference. 



The type was described from Comstock, Douglas Count}^, Oregon, 

 in beds supposed to be Miocene in age, but associated with it were 

 shells of Cardita planieostata and other characteristic Eocene fossils. 

 As the beds at Cherry Creek are certainl}' Eocene it would seem to sus 

 tain the contention that the beds at Comstock are also of this age. 



Localit;/. — Cherry Creek, Crook Coimty, Oregon. Collected by 

 Knowlton and Merriam, July, 1901 (U. S. Nat. Mus. , Nos. 9055, 9056). 



CiNNAMOMUM BeNDIREI n. sp. 



PI. X, fig. 4. 



Leaf membranaceous in texture, oblong-lanceolate in shape, long 

 wedge-shaped at base, apparently rather obtusely pointed at apex; 

 margin entire; petiole long and slender; midrib thick below, becoming 

 very thin above, with two or three pairs of thin secondaries in the 

 upper part which are at a low angle; lower pair of strong secondaries
