A single specimen from locality CS4 appears to be identical with the 
type material of this species from the Dakota sandstone of Kansas. The 
exact locality where the latter was collected is unknown, and it may have 
come from the older Mentor formation, which was not differentiated from 
the Dakota in Lesquereux’ s time. The question is not especially important 
in this connexion since detached pinnules of Podozamites are at best of 
slight stratigraphic value, since they are not only variable, but lack good 
diagnostic characters. 
Coniferophyta

Geinitzia jenneyi Ward (?) 
Geinitzia jenneyi Ward, 19th Ann, Kept. U.S. Geol. Surv., pt. 2, p. 676,

This species was described from the Fuson formation of Wyoming, 
and was based on material representing branches. These were minutely 
described by the author of the species and showed enlarged rhombic 
bolsters or leaf bases preserved in the form of casts. Whatever their botan- 
ical nature, and they are clearly referable to the Conifers but not certainly 
related to the genus Geinitzia, they seem to be the same as obscure casts of 
rather large branches from locality CS5 in the Upper Blairmore. 
Genus, sequoia Endlicher

This species is very fully discussed in my paper cited above. To it I 
refer, provisionally, certain fragments of coniferous twigs from the Upper 
Blairmore that agree with it perfectly. In the absence of cones, none of 
which] has been detected in the Upper Blairmore, it is entirely impossible 
to distinguish Sequoia condita from various other nominal species that 
have been referred to Glyptostrobus, Widdringtonites, Sphenolepis, etc., 
and I have, therefore, queried its identification in the Upper Blairmore. 
The species is characteristic of, and so far as is known is otherwise confined 
to, the Cheyenne sandstone of southern Kansas, where it is abundant and 
cone bearing. 
The Alberta occurrence is locality CH9.
