 JuGLANs ACUMINATA? Al. Br., Neues Jahrb., 1845, p. 170. 



The Bendire collection contains a sing-lc example that was referred 

 b}' Lesquereiix to this species. It does resemble this, but may not be 

 the same. 



LocaJiti/. — Brido-e Creek, (Irant County, Oreo-on. Collected by 

 Maj. Charles E. Bendire (U. S. Nat. Mus., No. 8006). 



JuGLANS CRYrXATA n. sp. 

 PL VI, figs. 4, 5. 



Leaflets membranaceous, broadly lanceolate, narrowed and unequal- 

 sided at base, apparantly acuminate at apex; margin denticulate 

 throuo'hout. the teeth short, rather blunt; midrib very thick; second- 

 aries numerous, 15 or more pairs, thin, alternate, close below, more 

 remote above, mostly camptodrome and sending line branches from 

 the outside to the teeth; nervilles mainly percurrent and at right 

 angles to the secondaries. 



This form is represented by three leaflets, none of which is quite 

 perfect. The largest, which is not figured, was probably about Itt cm. 

 long and is 5 cm. wide at a point evidently some distance above the 

 middle. The one next in size, shown in lig. 4, was 18.5 cm. long and 

 is 3.5 cm. wide. The smallest one, shown in tig. 5, is about 10 cm. 

 long and a little more than 2.5 cm. in width. Neither l)ase nor apex 

 is preserved in any case. 



This species appears to find its greatest afiinity with Juglans Crossii 

 Knowlton," from Green River, Wyoming, and other localities. The 

 leaflets, however, are smaller, relatively narrower, less unequal-sided, 

 and are toothed on both sides. 



Locality. — Bridge O-eek, Oregon. Collected by Merriam's expe- 

 dition in 1900. Types in Mus. Univ. Cal., Nos. 2502, 2503. 



Juglans, nut of. 



This is clearly a nut of Juglans, but the specimen is not well enough 

 preserved to permit of specific determination. Lesquereux, through 

 whose hands this specimen once passed, was inclined to identify it 

 doubtfully with J. troglodytaruin Heer,* but it seems best not to ven- 

 ture giving it a name at present. 



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

 Maj. Charles E. Bendire (U. S. Nat. Mus., No. 8492).
