This is the most clearly marked of all of the American species of 
Nageiopsis. It is found throughout the Potomac Group in the east, and 
has been recorded from the Knoxville and Horsetown beds of California, 
and from the Lakota formation of eastern Wyoming. In Alberta it is 
present in both the Kootenay and the Lower Blairmore, apparently rare 
in the former and more abundant in the latter. It may be briefly described 
as follows: stems much branched, relatively large. Leaves variable in 
size but constantly relatively very long and narrow, sometimes slightly 
falcate, acute, averaging about 3 mms. in maximum width, and from 2 to 7 
cms. in length. Veins longitudinal, parallel, about eight in number. 
Occurrence. Kootenay; locality CK1. Lower Blairmore; localities CH7, 
DB1, and DF 1.

There are two fragments in the Kootenay collection from locality 
CQ2 which probably represent what Fontaine described as Nageiopsis 
montanensis from the Kootenay at Geyser, Montana. The type was 
based upon a single detached leaf which is exactly like forms, which in the 
European Cretaceous, have been referred to Podozamites, and there is 
absolutely no evidence that any of these occurrences represent the genus 
Nageiopsis.

The specimen figured from the Lower Blairmore locality DB1 is all 
there is representing what may be a new species of Nageiopsis or an abnor- 
mal twig of a described species or even an abnormal twig of Torreya. It is 
clearly a branched conifer with small, elliptical parallel veined leaves of 
considerable consistency. The material is inadequate for a proper descrip- 
tion or identification, although the specimen is not unlike some of the 
variants of the Potomac species Nageiopsis ovaia.

This rather well-marked species is present in sparing amounts at two 
localities in the Lower Blairmore. It was described originally from material 
in the Kome beds of western Greenland and is not uncommon in the Bull 
Head Mountain sandstone of British Columbia. It should not be con- 
fused with the Kootenay species described by Dawson as Torreya dick - 
sonioides , which really represents Sequoia smiitiana. 
Occurrence . Lower Blairmore; localities CH5 and DB1.
