70 FOSSIL FLORA OF THE JOHN DAY BASIN, OREGON. [bull. 'J04. 



descril)0(l by Livsijuorcux as ])eiH<;' rounded at one (Mid and aciito at 

 the othei'. An examination sliow.s that the ])hintness deserii>ed is due 

 to the ends of one or two ))eino- broken or covered l)v matrix, whiU^ in 

 one well preserved ])oth ends are simihu- and acute. 



Locality. — Bridge Creek, (irrant County, Oregon. Collected by 

 C. D. Voy. (Types in Mus. Univ. Cal., Nos. 1765, 1766.) 



Family ANACAKDIACE^. 



Rhus Bendirei Lesq. 

 Rhus Bendirki Lesq., Proc. U. S. Nat. Mus., Vol. XI, p. 15, PI. IX, fig. 2, 1888. 



The type material consisted of the example figured and another 

 specimen with its counterpart. The figured specimen, it will be 

 noted, is oblanceolate in shape, about 10.5 cm. in length, 3.5 cm. in 

 width at the broadest point, and is narrowly wedge-shaped below and 

 acuminate above. Lesquereux regarded this as the terminal leaflet 

 and decided that the other specimen represented a lateral leaflet of 

 the same species. Of this latter he says: "To this I refer a small, 

 oblong-lanceolate leaflet, rounded in narrowing rapidly to the point 

 of attachment, very short-petioled, and areolation identical.''' This 

 is much smaller, being only 6 cm. in length and 2.5 cm. in greatest 

 width, and while it looks at first quite different, may belong to it. 

 The collection made by Dr. John C. Merriam in liK)0 contains two 

 specimens like the smaller leaflet. 



Locality. — Van Horn's ranch. South Fork of John Day River, about 

 12 miles west of Mount Vernon, Grant County, Oregon. Collected 

 by Maj. Charles E. Bendire (U. S. Nat. Mus., No. 2582). 



Rhus ? sp. Lesq. 

 PI. XIV, fig. 6. 



The original collection by Bendire contains a fragment of the base 

 of a leaf or leaflet that was referred by Lesciuereux to Rhus, but was 

 not included in his published list of species. It is impossible to make 

 out the whole outline, but it seems to have been obovate with a 

 broadly wedge-shaped, unequal-sided base. The margin appears to 

 have been provided with small, sharp teeth. The nervation consists of 

 a comparatively thick midrib and quite a number of thin secondaries, 

 those on the broader side of the blade being at a right angle and those 

 on the narrower side at an angle of al)out -l-i)°. The}' are apparently 

 camptodrome. 



It is clearly unsafe to attempt comparisons between this specimen 

 and other known species.
