KNowLTON.] DESCRIPTION OF SPECIES. 25 



appressed all around the branches, decurrino- at base." This in the 

 Tertiary Flora is amended to read: "' Branehlets .short, slender; leaves 

 at unequal distances, sometimes \ery close, two or three together, or 

 very distant, often dimorijhous. linear hmccolate, taper ])ointed, open 

 or curved liackward, decurrent; middle nerve indistinct." In the 

 discussion in the latter book Lesquereux emphasizes the fact that the 

 leaves arc "decurrent but not narrowed at base." 



All thing-.s considered this description at^rees well with the specimens 

 from Oregon, but the material from Elko, ol)tained during the sum- 

 mer of U>01 and presumably at or near the t3^pe locality, shows a slight 

 narrowing of the leaves at the })ase and a tendency to be less acute at 

 the apex. 



Locality, — Mascall beds, Van Horn's ranch and vicinity, about 12 

 miles west of Mount Vernon, Grant County, Oregon. Collected b}- 

 Maj. Charles E. Bendire (U. S. Nat. Mus., No. 2G10), and by Knowlton 

 and Merriam, July, ll,»Oi (U. S. Nat. Mus., Nos. 9029-9083).

The collections contain a number of examples that undoubtedly 

 belong to this species, although some of them do not agree in all par- 

 ticulars with certain of the published tigures. The branehlets are 

 rather small, with small leaves, but the latter are distinctly decurrent, 

 after the manner of tS. Lann^dorfii. 



The Bridge Creek material, which passed through the hands of 

 Newberry, was identified b}'^ him as Taxodium distichum miocenum.^ 

 but absolutely similar material was referred l)y Lesquereux to Sequoia 

 Langadorfii., and I ))elieve correctly so. 



This species, although not especially abundant at amy locality in thje 

 John Day Basin, is widely distributed, as may be seen from the fol- 

 lowing list of localities: 



Localities. — Bridge Creek. Collected by Rev. Thomas ('ondon (U. S. 

 Nat. Mus., No. T086), by Maj. Charles E. Bendire (H. S. Nat. Mus.,
