KNOWLTON.] DESCRIPTION OF SPECIES. 55 



Ulmus plurinervia Unger. 



Ulmii.s I'lATKiNERViA Unger. Lesquereux, Proc. U. S. Nat. Mus., Vol. XI, p. 18, 1888. 



A single .specimen with its counterpart is all that has been found of 

 this form. It is a little larger than the fio-ure given by Heer"* of the 

 Alaskan form, but is otherwise the same. 



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

 Grant County, Oregon. Collected by Maj. Charles PI Bendire (U. S. 

 Nat. Mus., No. 2020). 



Ulmus californica? Lesq. 



Ulmus californica Lesq., Foss. PI. Aurif. Gravel, p. 15, PL IV, fig. 2, 1878; Proc. 

 U. S. Nat. Mas., Vol. XI, p. 18, PL V. fig. 6 (there wrongly stated to be a figure 

 of Quercus horniana), 1888. 



The collections contain several examples, one of which was referred 

 by Lesquereux to his IThrms californica. The others are similar to 

 this and should properly go with it. The question as to whether they 

 are properly referred to this species is a rather difficult one to settle. 

 None of the leaves are nearly perfect nor do they agree in all particu- 

 lars with the types. The secondaries incline to arch slightly outward 

 instead of strongly upward. The character of the teeth can not be 

 made out satisfactorily. In view of these statements, it seems best to 

 question their reference to this species, and await future material to 

 settle the matter definitely. 



Locality. — Mascall beds, Van Horn's ranch, 12 miles west of Mount 

 Vernon, Grant County, Oregon. Collected by Maj. Charles E. Ben- 

 dire (U. S. Nat. Mus., No. 2621) and by Knowlton and Merriam, July, 

 1901 (U. S. Nat. Mus., Nos. 8983-8985). 



Planera Ungeri Ettingshausen. 



Planera Ungeri Ettingshausen. Lesquereux, Proc. U. S. Nat. Mus., Vol. XI, p. 19, 



1888. 



This species is represented by a single example and its counterpart, 

 and although not perfectly preserved may well belong to this form. 



Locality. — Mascall ])eds. Van Horn's ranch, Oregon. Collected by 

 Maj. Charles E. Bendire (U. S. Nat. Mus., No. 2531.) 



Family MORACE^. 



Ficus TENUiNERvis Lcsq. 



Ficus TENUINERVIS Lcsq., Cret. and Tert. FL, p. 164, PL XLIV, fig. 4, 1883; Proc. 

 U. 8. Nat. Mus., Vol. XI, p. 2:5, 1888. 



The single broken leaf upon which Lesquereux based its presence at 

 Cherry Creek remains unique. It is described and discussed at length 

 in the paper above quoted. 



Locality. — Cherry Creek, Crook County, Oregon. Collected I)y 

 Maj. Charles E. Bendire (U. S. Nat. Mus., No. 2179).
