The collection contains a single globular cone that is not to be dis- 

 tinguished from this species. 



Sequoia (cone), 

 pi. xxn, fig. i. 



There is a single cone in longitudinal section and still attached to the 

 long, slender peduncle. It is oblong as seen in section, being about 

 1 6 mm. long and 15 mm. broad at the base. The peduncle is 3.5 cm. 

 long and a little more than 2 cm. thick above. As nearly as can be 

 made out, about four scales on each side are shown in section. 



The long, thick, apparently naked peduncle is the same as that in 

 Sequoia heerii and this may belong to that species, but I am not cer- 

 tain from the section through the middle of the cone as to the shape 

 of the scales, and it seems best to consider it as different, at least for 



the present. 



Taxodium distichum miocenum Heer.

 figs. 6, 7, 1869. 



This is by far the most abundant species in the collection, for be- 

 sides some thirty or forty pieces of matrix containing hardly anything 

 else, there is scarcely a piece that does not bear branchlets of greater 

 or less size. 



Taxodium tinajorum Heer. 



Taxodium tinajorum HEER, Fl. Foss. Arct., p. 22, pi. i, figs. 1-5, 1869. 



There are several specimens that seem to belong to this species, 

 although it is difficult to separate them in all cases from the former 

 species.
