26 FOSSIL FLOKA OF THE JOHN DAI BASIN, OREGON, [bull. 204. 



Sequoia ,sp. (Cono). 

 PI. I, fig. 2. 



The original collection contains a large cone that was referred l)y 

 Lesquereux to Sequoia Langsdorfil,, but it does not appear to agree in 

 size with the cones usually assigned to that species. This cone is a 

 little more than 2,5 cm. in length and nearly 2 cm. thick, and stands 

 on a thick peduncle 7 mm. long and nearly 3 mm. thick. It has been 

 much crushed, and the shape of the scales can not be made out with 

 certainty. In general appearance, however, it seems to belong to 

 Sequoia, but the species must remain uncertain. 



Locality. — Van Horn's ranch, a])out 12 miles west of Mount Vernon, 

 Grant County, Oregon. Collected by Maj. Charles E. Bending (U. 8. 

 Nat. Mus., No. 8.510). 



Thuites sp. 



PI. I, fig. 3. 



Branchlets slender, alternate, leaves thickish, 4-ranked, imbricated, 

 the lateral ones broad-deltoid, rather obtuse pointed, others apparently 

 broader and more o])tuse, obscurely carinate on the back. 



The little fragment figured is all that has been thus far found in the 

 collections. The branchlets appear to be alternate and slender. As 

 nearl}^ as can be made out, the leaves are 4-ranked and very thick, with 

 obtuse apices. 



This form does not differ greatly from T. EhTenswcerdl Heer," from 

 the Miocene of Sachalin, and Spitzbergen. 



This has slender, alternate branchlets and thick 4-ranked leaves. 

 The}^ are more strongly, carinate on the back than oui's, but otherwise 

 there is no marked difference. As the branchlets from Oregon are so 

 small and not very well preserved, I have hesitated to identify them 

 with Heer's species, although they may all be the same. 



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

 County, Oregon. Collected by Merriam's expedition of 11)00 (Mus. 

 Univ. Cal., No. 879).

The collection contains numerous specimens that are referred to this 

 species. As I have pointed out on several occasions, there is more or 

 less confusion regarding the proper fixing of the limits of this species. 

 It is apparent that there is or has been a mixing of this with what has 



a Fl. Foss. Arct., Vol. 11, p. 3(5, PI. II, figs. 25, 26, 1870; idem, Vol. V, Abth. \, p. 23, PI. I, figs. 12-14, 1878.
