78 UNITED STATES GEOLOGICAL SURVEY— TERTIARY FLORA. 



leaves vary from three to seven millimeters long, averaging a little more than 

 one millimeter in width, generally linear or slightly enlarged toward the 

 point, of the same consistence as those of the former species, neither rigid 

 nor coriaceous, with a thin middle nerve. As seen in fig. 11a enlarged, they 

 are evidently decurring upon slender branchlets, none as thick as any of those 

 described and figured of Sequoia Langsdorffii. The cone, broadly globular 

 and flattened at the top, is larger than that of this last species, figured in Fl. 

 Arct., pi. ii, fig. 2, and about of the same form, and with few scales, but 

 smaller than that of pi. xlv, fig. 14, of the same work. Therefore the 

 difference in size is of no specific value, and also the total destruction of the 

 scales or leaflets upon the pedicel may be considered as resulting from 

 maceration. We have therefore merely, for specific character of this, the form, 

 the size of the leaves, and their distant, irregular position upon the slender 

 branches. Sequoia Langsdorffii, as figured in Flor. Alask. (pi. i, fig. 10), 

 and S. NordenskiUldi, Heer (Flor. Spitz., pi. iv, figs. 4, 34), have the 

 leaves linear-obtuse, but they are rigid, coriaceous, close to each other, longer 

 in the last species, twice as large in the former, with a thick middle nerve 

 in both. Numerous specimens, all from the same locality, represent frag- 

 ments or branchlets and cones with the same characters as those described 

 here.

Branches somewhat thick, flexaoas, pinnately divided; branchlets opposite, more rarely alternate, 

 open toward the base, and diverging, curving upward and erect from the middle; leaves biform, either 

 small, short, scaliform. Ungulate, pointed, at the base of the branchlets or covering them when young, 

 or longer, linear-oblong, enlarged in the middle, abruptly narrowed to a point, rarely obtuse, distichous, 

 close to each other, obliqne, gradually decreasing in length toward the top and the base of the branch- 

 lets; middle nerve distinct. 



Besides the branch figured here, a large number of more fragmentary 

 specimens, mostly branchlets, like fig. 26, have been sent from the same 

 locality. This fine species is described by Heer (loc. cit.) from Greenland 

 and from Spitzbergen specimens, and in the Baltic Miocene Flora from Kran- 

 tepcllen. North Germany. It is distinctly characterized by the form of its 

 generally short, distichous leaves, abruptly pointed, sometimes slightly obtuse,
