Podozamites lanceolatus (Lindley and Hutton) F. Braun 1 
Plate VI 
This so-called species, probably a composite, has a most extensive 
range, both geologic and geographic. To it I have referred a number of 
specimens from the Kootenay of Alberta. I have not found it in the 
Blairmore, although it has been recorded from other areas from horizons 
considerably younger than the Upper Blairmore. Although it is similar 
to some of the more elongate pinnule forms of Nageiopsis zamioides and 
might be confused with it, in fact may represent it, I separate it on the 
basis of the relatively longer and narrower pinnules, with finer and more 
numerous veins which converge somewhat toward the apex. There is no 
trace of spiral phyllotaxy or decurrent leaf bases, the rachis is not known 
to branch as does the stem of Nageiopsis, and the leaflets are irregularly 
spaced and less crowded, due perhaps to their deciduous habit. The 
specimens are not at all like Nageiopsis longifolia or Nageiopsis angustifolia . 
Among its many recorded occurrences Podozamites lanceolatus is known 
from other Kootenay localities, from the Bull Head Mountain sandstone, 
from the Knoxville of the Pacific Coast region, and from the Kome beds of 
western Greenland.

The objects here referred to Stenorachis are not uncommon at the 
Lower Blairmore locality DB1, four specimens having been discovered. 
They show a stout axis from 1*5 to 2*5 mms. in diameter, generally some- 
what curved, and preserved for maximum lengths of 6 cms. At intervals 
of about 1 to 1*5 cms. these axes give off branches alternately. These 
branches are slender, about 1 mm. in diameter, much curved, and about 
1 cm. in length. They appear to be invariably simple and not forked. 
At their tips they expand into pendant oval bodies of considerable con- 
sistency, which bodies are from 1 to 1*5 cms. in maximum and 8 to 11 
mms. in minimum diameter. They have a fluted appearance, not that of 
a seed, and are suggestive of from 4 to 8 large sporangia. 
These objects are unlike any Ginkgoalean or Cycadophyte fructifi- 
cations known to me, and although I fully recognize that this is not legi- 
timate evidence against such a relationship when the wealth of Mesozoic 
vegetative remains representing these two alliances is borne in mind, I 
cannot rid myself of the belief, suggested at first sight of them, that they 
represent modified fern pinnae enclosing large sac-shaped sporangia, or 
perhaps sori. That they are not simply unopened circulate pinnae is indi-
