DESCRIPTIONS OF SPECIES. 47 



more than one species may be represented, and Newberry has referred certain speci- 

 mens to J. macilenta Heer (loc. cit.j, as may be found discussed in this monograph 

 under Dammara borealis Heer (see p. 38), but I have been unable to consider them 

 as distinct from J. Jtypnoides. In fact, I am inclined to think that these two species 

 of Juniperus may very well be joined together, as the specific distinctions between 

 them are more or less vague. The vertical range of both species is practically 

 identical, but macilenta only has been recognized in the Old World.

Cone scale of a Conifer? 



PL II, fig. 38. 



This little cone scale is well defined, and yet it does not seem to be identifiable 

 with that of any described species, and apparently should not be included with any 

 of the cone scales described under the genus Dammara, but is somewhat suggestive 

 of that of certain cycads.

Typha? Hollick, Bull. Torrey Bot. Club, vol. 21, 1894, p. 63, pi. 180, fig. 9. 



These fragments apparently represent remains similar to those which it has been 

 the custom of paleobotanists to refer to the genus Typha, mostly from Tertiary 

 horizons." Any attempt, however, either to describe or to identify our specimens 

 specifically does not seem to be advisable.
